Medium [CVE-2026-59876] Prototype pollution vulnerability in Text Format extension
protobufjs compiles protobuf definitions into JavaScript (JS) functions. From 8.2.0 until 8.6.5, the protobufjs Text Format extension parsed string-keyed map entries using ordinary property assignment, allowing a map entry with key __proto__ to change the prototype of the returned map object instead of creating an own map entry in protobufjs/ext/textformat. This issue is fixed in version 8.6.5. A flaw was found in protobufjs. An attacker could exploit this to alter object behavior, potentially leading to information disclosure or other impacts. This Moderate-impact flaw in protobufjs allows an attacker to perform prototype pollution by providing specially crafted input to the Text Format extension. Red Hat severity: Moderate — CVSS 4.8 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N). Weakness: CWE-915. Under investigation: Cryostat 4; Red Hat Ansible Automation Platform 2; Red Hat Build of Podman Desktop; Red Hat Ceph Storage 9; Red Hat Enterprise Linux 8; Red Hat Openshift Data Foundation 4.

Medium [CVE-2026-59871] Denial of Service due to incorrect PAX path handling
node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.18, node-tar coerces all-digit PAX path and linkpath values in src/pax.ts to JavaScript numbers, causing downstream path handling such as normalizeWindowsPath(entry.path).split('/') to throw an uncaught TypeError. This issue is fixed in version 7.5.18. This vulnerability occurs when the library incorrectly converts specific archive path values into numbers, leading to an error during subsequent path processing. An attacker could exploit this to cause the application using node-tar to crash, resulting in a denial of service. 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-843. Affected products named by the advisory: Confidential Compute Attestation; Cryostat 4; Exploit Intelligence; Migration Toolkit for Containers; and 35 more.
Medium [CVE-2026-59875] Denial of Service via crafted archive with NUL bytes in metadata
node-tar is a tar archive manipulation library for Node.js. Prior to 7.5.17, node-tar does not strip NUL bytes from PAX path and linkpath records in src/pax.ts, allowing a crafted archive with values to reach fs.lstat or fs.open and terminate the process with an uncaught exception. This issue is fixed in version 7.5.17. A remote attacker could craft a malicious archive containing null characters (NUL bytes) in its metadata. When this archive is processed, the unstripped null characters can cause the application to terminate unexpectedly, leading to a Denial of Service (DoS). 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-170. Affected products named by the advisory: Confidential Compute Attestation; Cryostat 4; Exploit Intelligence; Migration Toolkit for Containers; and 35 more.
Medium [CVE-2026-54423] Arbitrary IPMI command execution via send_raw deployment step
In OpenStack Ironic before 37.0.1, an Ironic user with the ability to deploy nodes using the IPMI management interface can maliciously use the send_raw step to send arbitrary IPMI commands to a node, bypassing Ironic's access control. IPMI send_raw capability is exposed multiple ways, including via VendorPassthru interfaces (restricted to system admin) and other step based flows such as cleaning or servicing. This also means any malicious user with the ability to initiate manual cleaning and servicing flows with arbitrary steps can also execute this vulnerability. The Red Hat Product Security team has assessed the severity of this vulnerability as Moderate. While the IPMI send_raw functionality lacks a blocklist in certain step-based provisioning methods, exploitation requires privileges that are not available in default configurations. The SYSTEM_OR_OWNER_MEMBER_AND_LESSEE_ADMIN policy requires explicit administrator delegation of owner or lessee capabilities, and the automatic_lessee feature defaults to false and did not function correctly in shipped versions. This capability was introduced in upstream Ironic 22.1.0, which has not been shipped in any version of Red Hat OpenStack Platform or Red Hat OpenStack Services on OpenShift. Affected product named by the advisory: Red Hat OpenShift Container Platform 4.
Medium [CVE-2026-56297] Remote code execution or denial of service via use-after-free race condition
FreeRDP before 3.22.0 contains a use-after-free vulnerability in dvcman_channel_close and dvcman_call_on_receive due to improper synchronization of channel_callback access. A malicious RDP server can trigger a race condition by sending DYNVC_DATA and DYNVC_CLOSE messages concurrently, causing heap-use-after-free in the drdynvc client thread and potentially enabling remote code execution or denial of service. A flaw was found in FreeRDP. A malicious Remote Desktop Protocol (RDP) server can exploit a use-after-free vulnerability due to improper synchronization of channel callback access. This Moderate impact flaw in FreeRDP allows a malicious RDP server to trigger a use-after-free condition on the client by exploiting a race condition during dynamic virtual channel closure. Red Hat severity: Moderate — CVSS 5.6 (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L). Weakness: CWE-364.

Medium [CVE-2026-59997] SFTP security bypass due to command-line argument parsing flaw
internal-sftp in sshd in OpenSSH before 10.4 recognizes only the first 9 command-line arguments, which can be important if a later command-line argument would have helped to ensure the intended security properties of an SFTP connection. A flaw was found in OpenSSH. This limitation can prevent the application of intended security configurations for SFTP (SSH File Transfer Protocol) connections, potentially leading to a bypass of security properties. Red Hat severity: Moderate — CVSS 5.4 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N). Weakness: CWE-88. 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-2026-59996] `scp` file misplacement vulnerability during remote copy
scp in OpenSSH before 10.4 may place a file in the parent directory of an intended directory when the copy occurs between two remote destinations. A flaw was found in OpenSSH, a widely used tool for secure remote access. When a user attempts to copy files between two different remote systems using the `scp` command, the file might be incorrectly placed in a directory above the intended destination. This unintended file placement could lead to data integrity issues or, in some cases, unauthorized access to sensitive information if files are stored in an exposed location. Conditions for Exploitation: Exploitation requires specific user actions and conditions, as the vulnerability only triggers when a user explicitly initiates a file copy between two remote destinations using the scp command. Impact Limitations: The boundaries of the potential impact are highly contained. The flaw only results in unintended file placement within the parent directory of the target destination. It does not inherently lead to arbitrary code execution, denial of service, or privilege escalation, and any potential data exposure relies heavily on the existing permissions of the parent directory. Red Hat Enterprise Linux (RHEL) versions 6, 7, and 8 are not affected by this issue. Red Hat severity: Moderate — CVSS 4.6 (CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:L/A:L). Weakness: CWE-22.
Medium [CVE-2026-59995] sftp client allows attacker to control downloaded file location
sftp in OpenSSH before 10.4 does not properly constrain the location of downloaded files when "sftp server:/path." is used with an attacker-controlled server. A flaw was found in OpenSSH. The `sftp` client, when used to download files from a malicious server with the 'sftp server:/path.' command, does not properly restrict where those files are saved. This allows an attacker to control the download location, potentially overwriting existing files or placing malicious files in sensitive directories on the client system, which could compromise system integrity. Red Hat severity: Moderate — CVSS 5.4 (CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:L). Weakness: CWE-22. 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. Red Hat fixing advisory: RHSA-2026:37382. Affected products named by the advisory: Red Hat package: openssh.
Medium [CVE-2026-56000] GLX contextTags Use-After-Free in CommonMakeCurrent
Local attackers with a X connection able to provide GLX commit to the X server xorg-server before 21.2.24 and xwayland before 24.1.13 could cause a Heap Use After Free, due to CommonMakeCurrent() pointing into potentially reallocated memory. A flaw was found in the X.org X11 server, specifically within the GLX (OpenGL Extension to the X Window System) dispatch layer. A remote attacker can exploit this vulnerability by sending a series of crafted X11 requests. This can lead to a use-after-free condition, where the server attempts to write data to memory that has already been released. The primary consequence of this memory corruption is a denial of service, potentially causing the X server to crash. An Important use-after-free vulnerability in the X.org X11 server's GLX dispatch layer allows a remote, unauthenticated attacker to trigger a denial of service. This is considered Important due to the remote attack vector and the potential for unauthenticated denial of service. Red Hat severity: Important — CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-825. Affected Red Hat products: Red Hat Enterprise Linux 10; Red Hat Enterprise Linux 10.0 Extended Update Support; Red Hat Enterprise Linux 9; Red Hat Enterprise Linux 9.4 Update Services for SAP Solutions; Red Hat Enterprise Linux 9.6 Extended Update Support; Red Hat Enterprise Linux 8.
Medium [CVE-2026-15044] Unauthenticated access to AI guardrails and orchestrator APIs
A flaw was found in the TrustyAI Service Operator. When deploying services like gorch or NemoGuardrails, if a specific security setting is not enabled, these services can expose their communication channels without requiring users to prove their identity. This allows any other program within the cluster to access the AI guardrails and orchestrator without proper authorization. An attacker could exploit this to gain unauthorized access to sensitive information and potentially make limited changes to the AI models. By default, these services expose plain HTTP endpoints without authentication, enabling any co-located pod to access AI guardrails and orchestrator APIs. This could result in unauthorized access to sensitive data and potential manipulation of AI models. Red Hat severity: Moderate — CVSS 6.3 (CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N). Affected Red Hat products: Red Hat OpenShift AI (RHOAI). Red Hat does not currently list a fixing RHSA for this CVE.
Medium [CVE-2026-15063] Gorch port bypass when auth IS enabled
A flaw was found in the gorch service template, which is part of the trustyai-service-operator. Even when authentication is enabled, the gorch service exposes unproxied orchestrator and detector metrics ports. This allows any pod on the cluster network to directly access these ports, bypassing the kube-rbac-proxy and its authentication mechanisms. Red Hat severity: Moderate — CVSS 6.3 (CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:N). Weakness: CWE-306. Affected Red Hat products: Red Hat OpenShift AI (RHOAI). Red Hat does not currently list a fixing RHSA for this CVE.

Attackers can trigger memory and disk allocation failures to cause a heap-buffer-overflow read affecting any writer calling GetPixelIndex. This vulnerability in ImageMagick is rated as Low impact. Exploitation requires an attacker to trigger these specific resource exhaustion conditions, which limits the practical attack surface and reduces the overall risk of information disclosure on standard Red Hat deployments. Red Hat severity: Low — CVSS 3.3 (CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:L/I:N/A:L). 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.
Low [CVE-2026-56374] Denial of Service and Information Disclosure via heap buffer overflow in FTXT encoder
ImageMagick before 7.1.2-19 contains a heap buffer overflow vulnerability in the FTXT encoder due to missing boundary checks when parsing ftxt:format. Remote attackers can trigger an out of bounds read by crafting malicious FTXT image files to cause denial of service or information disclosure. A remote attacker could exploit this using a specially crafted FTXT image to cause a denial of service or disclose sensitive information. This low-impact heap buffer overflow in ImageMagick's FTXT encoder, caused by insufficient boundary checks, could lead to denial of service or information disclosure if a user opens a specially crafted FTXT file. Red Hat severity: Low — CVSS 3.3 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:L). 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.
Low [CVE-2026-15028] heap overflow OOB read while parsing a tar archive contains a PAX extended header
A flaw was found in libarchive. This vulnerability allows a remote attacker to trigger a heap overflow by providing a specially crafted tar archive. The issue occurs during the parsing of a PAX extended header containing a malformed SUN.holesdata sparse-file attribute. Successful exploitation could lead to a denial of service, making the system unavailable, or potentially allow for arbitrary code execution, giving the attacker control over the affected system. Conditions for Exploitation: Successful exploitation requires user interaction or a specific application workflow. Impact Limitations: Although the heap overflow has the potential to allow for arbitrary code execution, achieving this reliably is typically complex and highly dependent on the memory layout and protections of the specific application utilizing the library. In most common scenarios, the malformed archive will simply cause the parsing application to crash, resulting in a localized Denial of Service (DoS) rather than a full system compromise. Red Hat severity: Low — CVSS 3.9 (CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:L/I:N/A:L). Weakness: CWE-805.
