High [CVE-2026-74746] publish GC-visible tuple last
In the Linux kernel, the following vulnerability has been resolved: netfilter: flowtable: publish GC-visible tuple last nf_flow_table_iterate() only treats original-direction tuple nodes as owning entries. Publishing the original node first lets GC observe and free a flow while flow_offload_add() is still inserting the reply node. Publish the reply node first and the original node last so GC never sees a partially installed flow. KASAN can trigger slab-use-after-free read and write reports in the flowtable/rhashtable path (rht_deferred_worker, jhash, flow_offload_del, flow_offload_lookup, etc.). This vulnerability occurs due to a timing issue where the system's garbage collection can free a network flow while it is still being set up. This can lead to a 'use-after-free' condition, where the system attempts to access memory that has already been released. This memory corruption could potentially result in a system crash (denial of service) or, in certain circumstances, allow for arbitrary code execution. Red Hat severity: Important — CVSS 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-825. Affected Red Hat products: Red Hat Enterprise Linux 10; 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: kernel-rt.
High [CVE-2026-80540] Fix UVD decode image min size calculation
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Fix UVD decode image min size calculation This needs to use pitch instead of width. Also reject pitch over 4096 to avoid overflow. (cherry picked from commit b41c8cb12e202b220353332ab87dc01a11f69304) A flaw was found in the Linux kernel's `drm/amdgpu` component, specifically within the Universal Video Decoder (UVD) image size calculation. This vulnerability occurs because the minimum image size calculation incorrectly uses `width` instead of `pitch` and fails to reject `pitch` values exceeding 4096. An attacker could potentially exploit this integer overflow to cause a denial of service. Red Hat severity: Moderate — CVSS 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-190.
High [CVE-2026-80589] stop the timeout timer when releasing a never added disk
In the Linux kernel, the following vulnerability has been resolved: block: stop the timeout timer when releasing a never added disk disk_release() undoes blk_mq_init_allocated_queue() for a disk whose probe failed before add_disk(), but it only calls blk_mq_exit_queue(). Nothing there stops q->timeout, and that timer rolls forward: it stays pending until it next expires, not until the last request completes. So if the driver issued any I/O before adding the disk, the request_queue is freed while still linked into a timer wheel bucket. Affected products named by the advisory: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 9; Red Hat package: kernel-rt.
High [CVE-2026-80528] avoid fs reclaim while using current->journal_info
In the Linux kernel, the following vulnerability has been resolved: ceph: avoid fs reclaim while using current->journal_info handle_reply() stores a `ceph_mds_request` pointer in `current->journal_info` while filling the inode and dentry cache from an MDS reply. An allocation in this section can enter direct reclaim and prune dentries from another filesystem. If this dirties an ext4 inode, ext4 starts a JBD2 transaction. Affected products named by the advisory: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; and 1 more.
High [CVE-2026-80552] Ensure index for read/write regions are within range
In the Linux kernel, the following vulnerability has been resolved: s390/vfio_ccw: Ensure index for read/write regions are within range The introduction of the capability chain rightly clamped the region indexes to the range of the capabilities itself, but neglected to do so for the existing read/write regions which should also be enforced. This vulnerability occurs because the system fails to properly validate index ranges for read/write operations on existing regions. This oversight could allow an attacker to perform out-of-bounds memory access, potentially leading to information disclosure or system instability. Red Hat severity: Moderate — CVSS 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-125. Affected Red Hat products: Red Hat Enterprise Linux 10; 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: kernel-rt.
High [CVE-2026-80561] fix multiple unsafe decodes in decode_locker
In the Linux kernel, the following vulnerability has been resolved: libceph: fix multiple unsafe decodes in decode_locker() decode_locker() in cls_lock_client.c contains three unsafe decode operations that allow a malicious or compromised OSD to trigger slab-out-of-bounds reads: 1. ceph_decode_copy() at the locker_id_t name field has no preceding bounds check. With p == end after ceph_start_decoding() accepts struct_len=0, this reads sizeof(ceph_entity_name) = 9 bytes past the validated buffer boundary. 2. *p += sizeof(struct ceph_timespec) after the locker_info_t header is an unchecked pointer advance. A malicious OSD can position p past end, causing all subsequent _safe checks to pass against a bogus boundary. 3. len = ceph_decode_32(p) has no preceding bounds check, and the immediately following *p += len is uncapped. A malicious OSD can send len=0xffffffff, advancing p gigabytes past end and escaping the decode window entirely. Affected products named by the advisory: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9; and 1 more.
High [CVE-2026-57171] Arbitrary file write via path traversal in author generate commands
Compliance-trestle (Trestle) is a Python SDK and command-line tool for managing OSCAL compliance documents. In versions before 3.12.4 and versions 4.0.0 through 4.0.3, the catalog-generate, profile-generate, and ssp-generate author commands write generated Markdown to an attacker-influenced output path without path-traversal validation, allowing arbitrary file write outside the Trestle workspace. These commands join the user-supplied output argument onto the Trestle root and write to the result, but guard it only with an is_directory_name_allowed() task-name-collision check rather than the PathSecurityValidator.validate_local_path() guard used by the jinja command, so an absolute path or one containing traversal sequences escapes the workspace and writes files under an attacker-chosen location as the invoking process owner. The security boundary is crossed when a trusted CI job, shared service, or wrapper derives the output argument from repository-controlled, tenant-controlled, or otherwise untrusted data while expecting output to stay inside the workspace. When --force-overwrite is used, the selected output directory is first recursively deleted, extending the primitive to destruction of an attacker-chosen directory tree and enabling indirect code execution by overwriting files a pipeline later runs. This issue is fixed in versions 3.12.4 and 4.1.0.
High [CVE-2026-57170] Arbitrary code execution via Server-Side Template Injection
Compliance-trestle (Trestle) is a Python SDK and command-line tool for managing OSCAL compliance documents. In versions prior to 3.12.4 and 4.0.0 through 4.0.3, the custom Jinja2 include tags mdsection_include and md_clean_include re-parse the content of an included Markdown file as Jinja2 template code in a non-sandboxed environment, allowing server-side template injection that can lead to arbitrary code execution. The MDSectionInclude and MDCleanInclude tags in Trestle/core/jinja/tags.py pass included file content to Parser(self.environment,...).parse(), splicing it into the host template's compilation, and the environment is a plain jinja2.Environment rather than a SandboxedEnvironment, so any expressions in the file are evaluated with full access to the usual SSTI gadget chain. Because Trestle's Markdown writers emit OSCAL prose and component-description fields verbatim, applying delimiter neutralization only to parameter tables, attacker-controlled OSCAL data such as a control statement, part prose, or component description containing Jinja2 syntax flows into an included Markdown file and is executed when the include tag re-parses it. This issue is fixed in version 4.1.0. This vulnerability, known as Server-Side Template Injection (SSTI), allows an attacker to embed malicious Jinja2 syntax within OSCAL data.
High [CVE-2026-52776] Server-Side Request Forgery (SSRF) bypass via IPv4-mapped IPv6 and 0.0.0.0
Compliance-trestle (Trestle) is a tooling platform for managing compliance as code. In versions before 3.12.4 and versions 4.0.0 through 4.0.3, the URLSecurityValidator that guards trestle's remote-fetch paths against server-side request forgery can be bypassed to reach loopback, link-local, cloud-metadata, and internal network endpoints it was designed to block. The blocklist does not canonicalize IPv4-mapped IPv6 literals such as [::ffff:169.254.169.254], which resolve to IPv6Address objects that never match the blocked IPv4 ranges, and it does not block the unspecified address 0.0.0.0, which routes to local services on Linux and inside containers. An attacker who can supply or influence an OSCAL artifact that trestle fetches, such as a malicious profile whose imports reference one of these bypass URLs, can cause the HTTPSFetcher and SFTPFetcher paths to contact cloud instance-metadata services, loopback interfaces, or internal hosts. This issue is fixed in versions 3.12.4 and 4.1.0. The URLSecurityValidator, intended to prevent Server-Side Request Forgery (SSRF), contains a bypass vulnerability. This bypass occurs because the validator does not properly handle IPv4-mapped IPv6 addresses or the unspecified address 0.0.0.0. Affected product named by the advisory: File Integrity Operator.
High [CVE-2026-54757] Remote Code Execution via Server-Side Template Injection
Compliance-trestle (Trestle) is a Python SDK and command-line tool for managing OSCAL compliance documents. In versions before 3.12.4 and versions 4.0.0 through 4.0.3, Trestle is vulnerable to server-side template injection that can lead to remote code execution. This occurs because the MDCleanInclude and MDSectionInclude Jinja2 tags re-parse untrusted Markdown content as template source code using a non-sandboxed jinja2.Environment. An attacker who controls content that Trestle renders, such as a crafted workspace Markdown file, a third-party SSP document, or a YAML lookup-table value, can inject a Jinja2 expression that traverses Python object internals to execute arbitrary operating system commands in the context of the Trestle process. This issue is fixed in versions 3.12.4 and 4.1.0. This allows for remote code execution, enabling the attacker to run arbitrary operating system commands within the Trestle process. Red Hat severity: Important — CVSS 7.8 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H). Weakness: CWE-917. Affected Red Hat products: File Integrity Operator. Red Hat lists Red Hat Hardened Images as not affected. Red Hat does not currently list a fixing RHSA for this CVE.
High [CVE-2026-16645] Unauthorized access due to missing authorization
Missing Authorization vulnerability in Drupal PhotoSwipe - Responsive JavaScript Modal Image Gallery allows Forceful Browsing. This missing authorization vulnerability allows an attacker to perform forceful browsing, potentially leading to unauthorized access to sensitive information or resources. By exploiting this flaw, an attacker can bypass intended access controls. This Important vulnerability in Drupal PhotoSwipe does not affect Red Hat products as the vulnerable code is not present in the versions shipped with Red Hat offerings. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). Weakness: CWE-425. Red Hat lists Red Hat Developer Hub; Self-service automation portal 2 as not affected.
High [CVE-2026-80186] Stack Overflow in name2utf8 causes DoS and potential code execution
A stack-based buffer overflow vulnerability exists in BlueZ, the Linux Bluetooth protocol stack. A remote user within Bluetooth radio range can send a specially crafted Extended Inquiry Response (EIR) packet that causes a buffer overflow when the target device performs Bluetooth discovery. This vulnerability can lead to a Denial of Service (DoS) by crashing the bluetoothd service and may allow for arbitrary code execution. Red Hat severity: Important — CVSS 7.6 (CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H). Weakness: CWE-120. 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: bluez.
High [CVE-2026-68515] Heap out-of-bounds write in exrmultiview via crafted EXR files
OpenEXR is the reference implementation and specification for the EXR image format, widely used in the motion picture industry. In versions before 3.2.11, 3.3.0 through 3.3.12, and 3.4.0 through 3.4.13, exrmultiview can write past a heap allocation when it combines two attacker-supplied, individually valid scanline EXR files whose union dataWindow is not aligned to one view's channel subsampling. The utility allocates sampled channel storage using a truncated union_width / xSampling, then reads the sampled input through a Slice based on the misaligned union window, producing a heap out-of-bounds write. The trigger is normal public-tool processing, such as exrmultiview left A.exr right B.exr out.exr with crafted but valid inputs, so this is not solely an API or caller-precondition issue. This issue is fixed in versions 3.2.11, 3.3.13, and 3.4.14. A flaw was found in OpenEXR. A remote attacker could exploit this vulnerability by providing specially crafted EXR image files to the exrmultiview utility. When processing these files, the utility can write beyond its allocated memory on the heap, leading to a heap out-of-bounds write. This could allow an attacker to achieve arbitrary code execution or cause a denial of service (DoS) on the affected system. Exploitation requires a local attacker to persuade a user to process specially crafted EXR image files.
High [CVE-2026-79992] local shell command injection through the user field in emacs tramp
A flaw was found in Emacs TRAMP. A local attacker could exploit this vulnerability by processing maliciously crafted filenames. This occurs because TRAMP concatenates login arguments without proper sanitization, which are then passed to a local shell. Successful exploitation could lead to arbitrary code execution. This issue requires user interaction with a malicious file, limiting its remote exploitability. Red Hat severity: Important — CVSS 7.8 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-78. 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. Red Hat does not currently list a fixing RHSA for this CVE. Affected products named by the advisory: Red Hat package: emacs.
High [CVE-2026-55553] Credential leakage via cross-origin redirects
urllib is an HTTP client for Node.js that supports authentication, redirects, timeouts, and other request features. Prior to 4.9.1 and 2.44.1, urllib follows redirects through followRedirect but reuses caller-supplied options across origins. In src/HttpClient.ts, #requestInternal recursively calls this.#requestInternal(nextUrl.href, options, requestContext), causing options.headers and auth or digestAuth values to be reused when the redirect target has a different scheme, host, or port. Authorization, Cookie, Proxy-Authorization, x-api-key, x-auth-token, and x-access-token can therefore be sent to an attacker-controlled redirected origin, exposing credentials intended for the original origin and potentially allowing reuse against the original partner API or related services. No user interaction is required. This issue is fixed in versions 2.44.1 and 4.9.1. A flaw was found in urllib. This HTTP client for Node.js can be exploited by a remote attacker due to improper handling of cross-origin redirects. When following redirects, urllib reuses sensitive request headers, such as Authorization and Cookie, across different origins. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). Weakness: CWE-201. Affected Red Hat products: Red Hat Developer Hub; Self-service automation portal 2. Red Hat does not currently list a fixing RHSA for this CVE.
High [CVE-2026-63075] QUIC ACK-only packet retention can cause memory exhaustion
Issue summary: When OpenSSL processes QUIC traffic from a peer that repeatedly sends ack-eliciting packets while not acknowledging ACK-only responses, the QUIC stack can retain ACK-only packet metadata for the lifetime of the connection. Impact summary: A remote peer that can complete a QUIC handshake can cause connection-scoped memory growth which may lead to Denial of Service through memory exhaustion, especially with sustained traffic or many concurrent QUIC connections. CWE: CWE-770: Allocation of Resources Without Limits or Throttling Description: When the OpenSSL QUIC stack sends an ACK-only packet, there is no requirement by the QUIC protocol that the peer will acknowledge that ACK-only packet (i.e. it is itself not ack-eliciting). However, the OpenSSL implementation stores the metadata about the ACK frames regardless. In and of itself that's ok, but if a malicious peer establishes a connection, and then drives the connection such that ACK-only packets are forced from the OpenSSL implementation peer (i.e., by sending numerous PING frames), and then withholding any subsequent acks for ack-eliciting data, like legitimate data, said malicious peer can force inappropriate memory growth on the OpenSSL peer, potentially leading to a Denial of Service.
High [CVE-2026-79770] Denial of Service via crafted CSS selectors
Nokogiri versions before 1.19.3 contain regular expression denial of service vulnerabilities in the CSS selector tokenizer affecting string-literal and identifier tokenization. Attackers can inject adversarial CSS selectors into methods like Node#css, Node#at_css, and Searchable#search to cause exponential regex backtracking and denial of service. A flaw was found in Nokogiri. This injection can lead to regular expression denial of service (ReDoS) due to exponential regex backtracking, causing the application to become unresponsive. When processing untrusted user input passed to methods like Node#css, Node#at_css, or Searchable#search, an attacker can inject adversarial CSS selectors containing malicious string literals or identifiers. This triggers exponential regex backtracking within the parser, causing severe CPU exhaustion and leading to a Denial of Service (DoS) for the application thread. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-1333. Affected Red Hat products: Red Hat 3scale API Management Platform 2. Red Hat lists Red Hat Satellite 6 as not affected. Red Hat does not currently list a fixing RHSA for this CVE.
High [CVE-2026-79674] Information disclosure via path traversal in corpus-reader constructors
NLTK versions before 3.10.3 contain a path sandbox bypass vulnerability in corpus-reader constructors that allows attackers to read files outside the intended data root. Attackers can supply arbitrary corpus root paths to LinThesaurusCorpusReader and PanLexLiteCorpusReader constructors to access filesystem content and SQLite databases outside the pathsec sandbox boundary. A flaw was found in NLTK. A path traversal vulnerability exists in NLTK's corpus reader constructors LinThesaurusCorpusReader and PanLexLiteCorpusReader. An attacker capable of supplying arbitrary corpus root inputs can read files outside the intended data directory. Data exposure is restricted to files readable by the executing process user, and OS discretionary access controls or container isolation boundaries prevent privilege escalation beyond the application context. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). Weakness: CWE-22. Affected Red Hat products: Exploit Intelligence; Lightspeed Core; OpenShift Lightspeed; Red Hat Ansible Automation Platform 2; Red Hat OpenShift AI (RHOAI). Red Hat lists OpenShift Lightspeed as not affected. Red Hat does not currently list a fixing RHSA for this CVE.
High [CVE-2025-71406] Memory corruption via crafted XSLT
Nokogiri before 1.18.4 bundles a vulnerable version of libxslt (prior to 1.1.43) that contains two use-after-free vulnerabilities: CVE-2025-24855 (use-after-free of the XPath context node due to xsltEvalXPathStringNs leaking xpathCtxt->node) and CVE-2024-55549 (use-after-free related to excluded result prefixes/namespaces). Processing crafted XSLT can trigger memory corruption. Nokogiri 1.18.4 upgrades the bundled libxslt to 1.1.43 to resolve these issues. This vulnerability involves a use-after-free condition that can be triggered by processing specially crafted Extensible Stylesheet Language Transformations (XSLT). A remote attacker could exploit this to cause memory corruption, potentially leading to a denial of service or other impacts. Red Hat severity: Important — CVSS 7.8 (CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:N/I:H/A:H). Weakness: CWE-825. Affected Red Hat products: Red Hat 3scale API Management Platform 2; Red Hat Satellite 6. Red Hat does not currently list a fixing RHSA for this CVE.
High [CVE-2023-54354] Denial of Service via crafted XML schema
Nokogiri before 1.14.3 (CRuby implementation only, when using the packaged libxml2) bundles libxml2 v2.10.3, which is vulnerable to NULL pointer dereferences in XML Schema processing (xmlSchemaFixupComplexType, CVE-2023-28484, and xmlSchemaCheckCOSSTDerivedOK). An attacker who supplies a crafted/malformed XML schema can cause libxml2 to dereference a NULL pointer and potentially segfault, resulting in a denial of service. Nokogiri 1.14.3 upgrades the packaged libxml2 to v2.10.4 to resolve these issues. A flaw was found in Nokogiri, specifically in its bundled libxml2 library when processing XML schemas. Red Hat severity: Important — CVSS 7.5 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-476. Affected Red Hat products: Red Hat 3scale API Management Platform 2; Red Hat Satellite 6. Red Hat does not currently list a fixing RHSA for this CVE.
