Medium [CVE-2022-4994] wean fast IN from emulator_pio_in
In the Linux kernel, the following vulnerability has been resolved: KVM: x86: wean fast IN from emulator_pio_in Use __emulator_pio_in() directly for fast PIO instead of bouncing through emulator_pio_in() now that __emulator_pio_in() fills "val" when handling in-kernel PIO. vcpu->arch.pio.count is guaranteed to be '0', so this a pure nop. emulator_pio_in_emulated is now the last caller of emulator_pio_in. No functional change intended. Red Hat severity: Low — CVSS 5.5 (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H). Weakness: CWE-908. Affected Red Hat products: Red Hat Enterprise Linux 6; 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: kernel-rt.
Medium [CVE-2026-62343] Denial of Service via heap buffer over-write in morphology operation with invalid kernel
ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to 6.9.13-51 and 7.0.1-0 and above prior to 7.1.2-26, an invalid kernel can cause a heap buffer over-write when performing a morphology operation with a user supplied kernel. This issue has been fixed in versions 6.9.13-51 and 7.1.2-26. A local user could provide a specially crafted, invalid kernel during a morphology operation. This action could trigger a heap buffer over-write, leading to a denial of service (DoS) for the ImageMagick application. This vulnerability primarily impacts the availability of the image processing service. Red Hat severity: Moderate — CVSS 4.7 (CVSS:3.1/AV:L/AC:H/PR:N/UI:R/S:U/C:N/I:N/A:H). Weakness: CWE-805. 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-2026-64685] Information Disclosure via Crafted Image File
ImageMagick is free and open-source software used for editing and manipulating digital images. In versions prior to 7.1.2-27, the BGR decoder does not check for an end-of-file in every location so a crafted image could result in an heap buffer over-read. This issue has been fixed in version 7.1.2-27. A remote attacker could exploit a vulnerability in the BGR decoder by providing a specially crafted image file. This flaw, caused by a missing end-of-file check, can lead to a heap buffer over-read, potentially resulting in the disclosure of sensitive information. Moderate: ImageMagick's BGR decoder is vulnerable to a heap buffer over-read when processing specially crafted image files. This flaw could lead to information disclosure if applications using ImageMagick process untrusted images, potentially exposing sensitive memory contents. The impact is limited to information disclosure and does not directly enable arbitrary code execution. Red Hat severity: Moderate — CVSS 5.3 (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N). 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-2026-16728] Response desynchronization via retry interceptor with mismatched Content-Length
Response desynchronization via retry interceptor with mismatched Content-Length. Red Hat rates this moderate (CVSS 4.8). Weakness: CWE-444. Red Hat lists fixing advisory RHSA-2026:48273 with package nodejs26-main-26.5.1-1.5.hum1, nodejs24-main-24.18.1-0.1.hum1.
Medium [CVE-2026-54249] Information disclosure through unvalidated file references.
Pydantic AI is a Python agent framework for building Generative AI applications. In versions 1.65.0 through 1.105.0, and 2.0.0b1 through 2.0.0b5, a client that submits message history to a Pydantic AI UI adapter (such as the Vercel AI adapter) can reference arbitrary files in the application's model-provider or cloud-storage account. While file URL parts are validated against a scheme allowlist, UploadedFile references — which point to a file by provider file ID or cloud-storage URI (e.g. s3://…, gs://…) — were forwarded without validation. Because the provider resolves an UploadedFile using the server-side identity (IAM role, service account, or provider API key) rather than the client's, an attacker can craft message history to make the server read objects from its own account or other tenants, given a referenceable identifier. Exploitation requires a valid file identifier, which is not always unguessable depending on how the application names objects. This issue has been fixed in versions 1.106.0 and 2.0.0b6. A flaw was found in pydantic-ai. A remote attacker could exploit this vulnerability by submitting crafted message history containing unvalidated file references. This could trick the server into reading arbitrary files from its own cloud storage accounts, such as Amazon S3 or Google Cloud Storage, or from other tenants.
Medium [CVE-2026-46678] Server-Side Request Forgery (SSRF) bypass exposes cloud credentials.
Pydantic AI is a Python agent framework for building Generative AI applications. In versions 1.56.0 through 1.98.0, when an application opts a URL into force_download='allow-local' (disabling the default block on private/internal IPs), the cloud-metadata blocklist could be bypassed by encoding the metadata IP in an IPv6 transition form (IPv4-mapped IPv6, 6to4, or NAT64), exposing cloud IAM short-term credentials on dual-stack or translated networks. This is an incomplete fix of GHSA-2jrp-274c-jhv3 / CVE-2026-25580, whose remediation did not hold for IPv6-encoded forms of the metadata IPs. An application is affected only if it explicitly opts a FileUrl (ImageUrl, AudioUrl, VideoUrl, DocumentUrl) into force_download='allow-local' on a URL influenced by untrusted input; it is not affected when using bundled integrations to ingest user input (Agent.to_web / clai web, VercelAIAdapter, AGUIAdapter / Agent.to_ag_ui), since they do not propagate force_download from external data, nor when downloading only from developer-controlled URLs. This issue has been fixed in version 1.99.0. When an application is configured to allow local file downloads from untrusted URLs, a Server-Side Request Forgery (SSRF) vulnerability exists. This flaw allows an attacker to bypass existing security controls by encoding cloud metadata IP addresses using IPv4-mapped IPv6 formats.
Medium [CVE-2026-65975] Remote clients can execute server tools with forged arguments due to improper message sanitization.
Pydantic AI is a Python agent framework for building applications and workflows with Generative AI. In versions 1.88.0 up to but not including 1.107.1 and 2.0.0b1 up to but not including 2.5.0, the UI adapters (AG-UI via Agent.to_ag_ui()/AGUIAdapter, and Vercel AI via VercelAIAdapter) use sanitize_messages to strip unresolved ("dangling") client-submitted tool calls from untrusted message history before it reaches the agent, a defense-in-depth default that prevents the agent from executing tool calls the model never emitted. However, the strip anchored to a message index computed before sanitization ran, so when a trailing client message sanitized to empty and was dropped (for example a client system message under the default manage_system_prompt='server'), a preceding assistant response carrying an unresolved tool call became the new tail and was dispatched without inspection. As a result, a remote client could cause a registered, non-approval server tool to run with client-supplied arguments rather than arguments the model produced. The impact is bounded by what the affected tools do and is most significant for applications that gate tool execution in a model-request hook (before_model_request / after_model_request), since a forged call skips the model turn and bypasses that guardrail; approval-gated tools (requires_approval=True) are not auto-executed by this path.
Medium [CVE-2026-13346] Arbitrary file installation via malicious package indexes
pip would incorrectly handle doubly-encoded package URLs from indexes allowing for files to be installed to arbitrary locations on disk even when installing wheels. This vulnerability requires downloading or installing a package from a malicious package index to succeed, malicious packages alone are not able to exploit this vulnerability. Note that this vulnerability only materially impacts users running `pip download` with the `--only-binary` option as installing source distributions from an untrusted index is already an unsafe operation that executes code during install time. A flaw was found in pip. When processing doubly-encoded package URLs from malicious package indexes, pip incorrectly handles the file paths. A remote attacker could exploit this by convincing a user to download or install a package from such an index. This could allow for files to be installed to arbitrary locations on the system, potentially leading to system compromise. Red Hat severity: Moderate — CVSS 5.9 (CVSS:3.1/AV:N/AC:H/PR:L/UI:R/S:U/C:L/I:H/A:L). Weakness: CWE-22. Affected Red Hat products: Red Hat Hardened Images; Red Hat Enterprise Linux 10; 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-2026:48788. Affected products named by the advisory: Red Hat package: python-pip.
Medium [CVE-2026-62995] JWT Malleability via Non-Standard Padding
joserfc is a Python library that provides an implementation of several JSON Object Signing and Encryption (JOSE) standards. in versions 1.7.1 and prior, joserfc accepts JWTs with trailing padding (==) which are not conforming to the JOSE specifications. This leads to malleability of the JWTs when consumed by joserfc. Depending on this application this might or not be an issue. This could lead to bypass of token revocation or anti-replay protection when implemented as a deny list of tokens or a deny list of token hashes. Note that ECDSA JWS are always malleable because of the malleability of ECDSA signatures (first test case in the code bellow). This makes a scheme which assumes that JWTs are not malleable brittle. However for other signatures (or MAC) schemes it might make sense to assume non malleability of the token. This issue has been fixed in version 1.7.2. This vulnerability allows the library to accept JSON Web Tokens (JWTs) that include non-standard trailing padding. An attacker could exploit this to create malleable JWTs, potentially bypassing security mechanisms like token revocation or anti-replay protection. This could lead to unauthorized access or continued use of tokens that should be invalid. Affected products named by the advisory: Red Hat Hardened Images; Lightspeed Core; Migration Toolkit for Applications 8; OpenShift Lightspeed; and 3 more.
