Medium [CVE-2026-15712] HTTP/2 GOAWAY frame parsing heap buffer over-read via invalid NUL-termination assumption
A heap buffer over-read vulnerability was discovered in libsoup's (versions: libsoup 3.0 to 3.7.0) HTTP/2 connection tracking framework. When the library processes an HTTP/2 GOAWAY frame, it improperly handles the "Additional Debug Data" payload by assuming the data stream is a safely NUL-terminated C-string. Because the parser lacks strict length-boundary verification before reading this data, a remote, unauthenticated attacker can intentionally send a malformed GOAWAY frame missing the appropriate null delimiter. This causes the library to read past the end of the allocated buffer, triggering an application crash that results in a denial of service (DoS), or potentially exposing fragments of memory contents. This vulnerability poses a moderate impact to system confidentiality and availability for software implementations leveraging libsoup for HTTP/2 client or server communications. An unauthenticated network adversary can manipulate frame characteristics to force memory parsing out-of-bounds without requiring special system privileges or user interaction. While primarily resulting in a denial of service via a segmentation fault, the risk of data exposure from adjacent heap allocations places this as a notable security boundary failure within the protocol decoding stack. Red Hat severity: Low — CVSS 5.9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-125.
Medium [CVE-2026-59884] Denial of Service via crafted BER input
pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the BER decoder shared by the CER and DER codecs parses long-form tags by accumulating continuation octets without an upper bound on the tag ID size, allowing a crafted input to force construction of an arbitrarily large integer with CPU cost growing quadratically and to trigger unhandled ValueError exceptions in Python 3.11+ error formatting paths. Any application decoding untrusted BER, CER, or DER input is affected. This issue is fixed in version 0.6.4. A remote attacker can exploit this by providing a specially crafted input, leading to the construction of an arbitrarily large integer. A flaw was found in pyasn1's BER decoder. Many common uses of pyasn1 involve parsing trusted certificates or local configuration and are not exposed to this flaw. The realistic impact is a denial-of-service of the consuming Python process, with automatic recovery in typical service deployments. Red Hat severity: Moderate — CVSS 5.9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-770. Affected products named by the advisory: Red Hat AI Inference Server 3.3; Red Hat Enterprise Linux AI 3.3; Red Hat Hardened Images; Red Hat OpenShift AI 3.3; and 30 more. Affected products named by the advisory: Red Hat OpenShift AI 3.4; Exploit Intelligence; Lightspeed Core; Migration Toolkit for Applications 8; and 26 more.
Medium [CVE-2026-15392] DBD::File: Arbitrary file read/write via symlink vulnerability
DBD::File versions before 1.651 for Perl do not ensure the table file is not a symlink to an untrusted location. The complete_table_name method builds the absolute table file path without checking whether the file is a symbolic link. A link inside the data directory can point to a table file at any path outside of the configured f_dir and f_dir_search directories. Callers of file-based drivers can read or write files outside of the data directory. This oversight allows a local attacker to create a symbolic link within the data directory that points to an arbitrary file outside of the intended data storage. Consequently, file-based drivers can be tricked into reading from or writing to unauthorized files, potentially leading to information disclosure or data corruption. This Moderate flaw in DBD::File allows a local attacker to achieve arbitrary file read and write access. Red Hat severity: Moderate — CVSS 6.3 (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:L). Weakness: CWE-59. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Will not fix / out of support: Red Hat Enterprise Linux 6. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: perl-dbi.
Medium [CVE-2026-15043] DBI::SQL::Nano: DBI::SQL::Nano: Incorrect SQL operator evaluation can lead to incorrect data filtering.
DBI::SQL::Nano versions from 1.42 before 1.651 for Perl have inverted = SQL operators on text. DBI::SQL::Nano, DBI's built-in mini-SQL engine, evaluated WHERE predicates incorrectly in some cases. In the non-numeric string branch of the is_matched method, = was evaluated using Perl's le operator. SQL::Nano is the fallback query engine for DBI's file-backed drivers (DBD::File, DBD::DBM, CSV-style drivers) whenever SQL::Statement is not installed, and is forced whenever DBI_SQL_NANO=1. Queries over such tables use these predicates directly. The impact depends on the context. Where an application relies on a WHERE clause to filter file-backed data for policy or authorization, an inverted = comparison silently returns the wrong rows. This vulnerability occurs because the engine incorrectly evaluates SQL operators for text comparisons, specifically inverting the logic for "less than or equal to" and "greater than or equal to" operations. This can lead to applications that rely on these comparisons for filtering data, such as for policy or authorization, silently returning incorrect results. A Moderate impact flaw in perl-DBI's SQL::Nano engine can lead to incorrect data filtering. This issue arises when applications use file-backed drivers with SQL::Nano as the fallback SQL engine, causing text comparison operators (` =`) to be inverted.
Medium [CVE-2026-0716 +1] incomplete fix for CVE-2026-0716: out-of-bounds read in libsoup websocket frame processing (unmasked path)
The fix for CVE-2026-0716 (commit 6ff7ef0, libsoup 3.6.6) placed the integer overflow guard inside the if (masked) block, leaving unmasked server-to-client frames unprotected. A malicious WebSocket server can send a crafted unmasked frame with a payload length near UINT64_MAX to trigger an OOB read in a libsoup-based client when max_incoming_payload_size is set to 0. This vulnerability is rated Moderate for Red Hat because it requires a non-default configuration where max_incoming_payload_size is explicitly set to 0 or unset in libsoup's WebSocket frame processing. In typical Red Hat deployments, this configuration is not enabled by default, limiting the exposure to memory disclosure or application instability. Red Hat severity: Moderate — CVSS 4.8 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:L). Weakness: CWE-125. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: libsoup3.
Medium [CVE-2026-40468] Memory corruption via integer overflow
Integer overflow vulnerability has been found in "builtin.c" program file of gawk. This issue may lead to memory exhaustion on the hosting operating system and could be used to overwrite gawk heap metadata and objects with attacker-controlled bytes. It affects gawk in versions 5.4.0 and below. A flaw was found in gawk. An integer overflow vulnerability could allow a local attacker to cause memory exhaustion, leading to a denial of service. This flaw may also enable an attacker to corrupt gawk's internal memory, potentially leading to system instability. This could lead to system instability or a denial of service on affected Red Hat products, requiring local access to execute a malicious gawk script. Red Hat severity: Moderate — CVSS 4.4 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L). Weakness: CWE-190. Affected Red Hat products: Red Hat Hardened Images; Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat OpenShift Container Platform 4.

Medium [CVE-2026-40467] Denial of Service due to Use After Free vulnerability in io.c
Use After Free vulnerability has been found in "io.c" program file of gawk (do_getline_redir() routine). This issue may lead to a crash. It affects gawk in versions 5.4.0 and below. A flaw was found in gawk. This vulnerability can be triggered by an attacker, potentially leading to a system crash and causing a Denial of Service (DoS). This flaw, affecting gawk in Red Hat Hardened Images, requires a local attacker with low privileges to trick a user into interacting with specially crafted input, limiting its immediate impact. Red Hat severity: Moderate — CVSS 4 (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L). Weakness: CWE-825. Affected Red Hat products: Red Hat Hardened Images; Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; Red Hat OpenShift Container Platform 4.

Medium [CVE-2026-61861] Use-after-free vulnerability leading to denial of service or code execution
ImageMagick before 7.1.2-26 contains a use-after-free vulnerability in the FormatMagickCaption method when memory allocation fails. Attackers can trigger memory allocation failures to cause a dangling pointer to reference freed memory, potentially enabling denial of service or code execution. A flaw was found in ImageMagick. Red Hat severity: Moderate — CVSS 5.9 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-825. Affected Red Hat products: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: imagemagick.
Medium [CVE-2026-61465] Denial of Service via crafted image due to missing memory allocation check
ImageMagick before 7.1.2-26 and 6.9.13-51 is missing a check for the allowed memory allocation limit in matrix-backed operations such as -canny. An attacker can supply a crafted image that causes ImageMagick to allocate more memory than permitted by the configured policy, resulting in a denial of service. A flaw was found in ImageMagick. A remote attacker could provide a specially crafted image, causing the software to allocate more memory than permitted by its configuration. This can lead to a denial of service (DoS), making the system or application unavailable to legitimate users. Red Hat severity: Moderate — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). Weakness: CWE-770. Affected Red Hat products: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: imagemagick.
Medium [CVE-2026-61857] Application crashes via malicious XMP profiles
ImageMagick before 7.1.2-26 contains a heap use-after-free vulnerability caused by missing null check when parsing XMP profiles. Attackers can craft malicious image files with specially crafted XMP data to trigger the vulnerability and cause application crashes. A flaw was found in ImageMagick. This vulnerability allows a remote attacker to cause the application to crash. The issue stems from improper handling of XMP (Extensible Metadata Platform) profiles within image files. By crafting a malicious image with specially designed XMP data, an attacker can trigger a heap use-after-free condition, leading to a denial of service. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H). Weakness: CWE-476. Affected Red Hat products: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: imagemagick.
Medium [CVE-2026-56372] Information Disclosure and Denial of Service
ImageMagick before 7.1.2-19 contains a heap buffer overflow vulnerability in the magnify operation that allows attackers to read out of bounds memory. An unrecognized magnify:method value triggers an out of bounds read, potentially exposing sensitive information or causing denial of service. A flaw was found in ImageMagick. This heap buffer overflow vulnerability, identified as CWE-122 (Heap-based Buffer Overflow), occurs in the magnify operation when processing an unrecognized `magnify:method` value. An attacker could exploit this by providing a specially crafted input, leading to an out-of-bounds read. This could potentially expose sensitive information or cause a denial of service (DoS) to the system. Red Hat severity: Moderate — CVSS 6.1 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H). Weakness: CWE-125. Affected Red Hat products: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: imagemagick.
Medium [CVE-2026-52747] Security rule bypass due to incorrect handling of line breaks in form data
ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. Prior to 3.0.16, the multipart/form-data request body parser in libmodsecurity silently removes embedded line breaks from non-file form-field values before exporting them to ARGS and ARGS_POST because src/request_body_processor/multipart.cc overwrites reserved bytes in m_reserve instead of appending the current buffer. This creates a parser differential between ModSecurity and backend applications that preserve line breaks in form fields, allowing rules that inspect ARGS or ARGS_POST to miss payloads whose dangerous syntax depends on a line break. This issue is fixed in version 3.0.16. This bypass could lead to the execution of dangerous payloads that rely on line breaks, potentially resulting in a security compromise. This issue is classified as Moderate severity primarily because: Conditions for Exploitation: Successful exploitation requires a specific scenario where the backend application preserves line breaks and is inherently vulnerable to a payload that utilizes those line breaks. Additionally, the ModSecurity configuration must rely on rules inspecting the affected ARGS or ARGS_POST variables to allow the bypass to occur.
Medium [CVE-2026-52761] Web Application Firewall rules bypass due to incorrect UTF-8 to Unicode transformation
ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx. From 3.0.0 through 3.0.15, the t:utf8toUnicode transformation in src/actions/transformations/utf8_to_unicode.cc produces wrong output on i386 architecture because snprintf uses sizeof on a char pointer rather than the length of the unicode buffer, allowing rules that use this transformation to be bypassed on i386 architecture. This issue is fixed in version 3.0.16. The `t:utf8toUnicode` transformation function, responsible for converting UTF-8 encoded characters to Unicode, generates incorrect output on i386 architectures. This vulnerability allows an attacker to bypass WAF rules, potentially enabling malicious requests to reach the protected application. The consequence is a moderate integrity loss due to the circumvention of security controls. Conditions for Exploitation: Exploitation is strictly limited to 32-bit (i386) architectures, which reduces the likelihood of exploitation in typical deployments. Furthermore, it requires the ModSecurity configuration to actively use rules that rely on the affected transformation function. Impact Limitations: The vulnerability functions solely as a WAF rule bypass and does not directly cause privilege escalation, data corruption, or arbitrary code execution on the host system.
Medium [CVE-2026-49844] Malformed JSON output due to improper encoding of floating-point values
Improper encoding of non-finite floating-point values during MapMessage JSON serialization in Apache Log4j API produces output that is not valid JSON. The fix for CVE-2026-34481 did not cover all code paths: when a MapMessage contains a non-finite IEEE 754 value (NaN, Infinity, or -Infinity), MapMessage.asJson() emits the corresponding bare token. RFC 8259 does not permit these tokens, so a conformant parser rejects the resulting document. The defect is reachable only when both of the following conditions hold: * The application uses the message resolver of JsonTemplateLayout or any other layout that relies on MapMessage.asJson() or MapMessage.getFormattedMessage(new String[]{"JSON"}). * The application logs a MapMessage that contains an attacker-controlled floating-point value. An attacker who can supply a non-finite value can cause the affected layout to emit malformed JSON, which may corrupt the enclosing log record or disrupt downstream log ingestion and parsing. Users are advised to upgrade to Apache Log4j API 2.25.5 or 2.26.1, both of which emit RFC 8259-compliant JSON for non-finite values. This can corrupt log records or disrupt downstream log ingestion and parsing, potentially leading to a Denial of Service (DoS) or information integrity issues.
Medium [CVE-2026-57157] Out-of-bounds read leads to information disclosure and denial of service
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, FreeRDP server implementations with the MS-RDPECAM camera device enumerator channel enabled scan attacker-supplied DeviceName and VirtualChannelName fields for a NUL terminator in channels/rdpecam/server/camera_device_enumerator_main.c and then dereference once past the scan bound, allowing a malicious RDP client to trigger a 1- to 2-byte out-of-bounds heap read. This issue is fixed in version 3.28.0. A malicious RDP client can exploit this by manipulating the DeviceName and VirtualChannelName fields, which can lead to information disclosure and denial of service. Red Hat severity: Moderate — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:L). Weakness: CWE-125. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: freerdp.
Medium [CVE-2026-57158] Information disclosure via truncated RDPGFX planar payload
FreeRDP is a free implementation of the Remote Desktop Protocol. From 3.21.0 before 3.28.0, FreeRDP clients using the GFX pipeline contain an incomplete fix for CVE-2026-23530 in planar_decompress_plane_rle_only in libfreerdp/codec/planar.c, allowing a malicious RDP server to send a truncated RDPGFX_CMDID_WIRETOSURFACE_1 planar payload that reads one byte past the input buffer. This issue is fixed in version 3.28.0. FreeRDP clients using the Graphics (GFX) pipeline are vulnerable to an out-of-bounds read. A malicious RDP server can exploit this by sending a specially crafted, truncated RDPGFX_CMDID_WIRETOSURFACE_1 planar payload. This can lead to reading one byte beyond the intended buffer, potentially disclosing sensitive information or causing a denial of service. Red Hat severity: Moderate — CVSS 5.4 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L). Weakness: CWE-125. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: freerdp.
Medium [CVE-2026-15146] Server-Side Request Forgery via FTP PASV response IP address validation bypass
GNU Wget does not validate the IP address provided by an FTP PASV response while operating in FTP passive mode. A malicious FTP server, or an HTTP server that redirects to an FTP URL, can exploit this behavior to redirect Wget’s data connection to an arbitrary IP address and port. This allows an attacker to forge server-side requests (SSRF) from the machine running Wget, potentially accessing localhost services or internal network resources. A flaw was found in Wget. Red Hat severity: Moderate — CVSS 5.9 (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L). Weakness: CWE-918. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9. Will not fix / out of support: Red Hat Enterprise Linux 6; Red Hat Enterprise Linux 7. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: wget.
Medium [CVE-2026-8609] Denial of Service via unbounded memory growth in OAuth login route
An unauthenticated attacker can repeatedly call Grafana's OAuth login route with unique values, causing unbounded memory growth that can eventually exhaust memory and crash the Grafana instance (denial of service). A flaw was found in Grafana. This results in a denial of service for legitimate users. Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L). Weakness: CWE-770. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 10.0 Extended Update Support; Red Hat Hardened Images; Red Hat Ceph Storage 9; Red Hat Enterprise Linux 9. Red Hat lists Multicluster Global Hub; Red Hat Advanced Cluster Management for Kubernetes 2; Red Hat Ceph Storage 5; Red Hat Ceph Storage 6; Red Hat Ceph Storage 7; Red Hat Ceph Storage 8; Red Hat Enterprise Linux 8; Red Hat Hardened Images as not affected. Red Hat fixing advisory: RHSA-2026:54178, RHSA-2026:67517, RHSA-2026:63164, RHSA-2026:63165, RHSA-2026:65157. Affected products named by the advisory: Red Hat package: grafana.
Medium [CVE-2026-33382] Denial of Service via excessive memory allocation from large API request payloads
Several Grafana API endpoints, some of them unauthenticated, do not limit the size of the request body before processing it. An attacker can send very large payloads that force excessive memory allocation, potentially exhausting memory and causing a denial of service. A flaw in Grafana's API endpoints allows remote attackers to send excessively large request bodies without authentication. This exhausts server memory, resulting in a complete denial of service (DoS). Moderate: This denial of service vulnerability in Grafana stems from a lack of request body size limits on certain API endpoints, some of which are unauthenticated. Exploitation by a remote attacker sending large payloads can exhaust system memory, leading to service unavailability. The impact is assessed as Moderate because it primarily affects the availability of the Grafana application rather than compromising data or executing arbitrary code. Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L). Weakness: CWE-770. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 10.0 Extended Update Support; Red Hat Hardened Images; Red Hat Ceph Storage 9; Red Hat Enterprise Linux 9. Affected products named by the advisory: Red Hat package: grafana.
