USN-8575-1: Linux kernel vulnerabilities

Maxim Suhanov discovered that the NTFS file system implementation in the Linux kernel did not properly validate file name length in certain situations, leading to an out-of-bounds read. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could expose...

USN-8574-1: Linux kernel (GCP FIPS) vulnerabilities

It was discovered that some AMD processors did not properly clear data in the floating point divider unit during speculative execution. A local attacker could use this to expose sensitive information. CVE-2025-54505 It was discovered that some AMD Zen 2 processors did not properly isolate shared...

CVE-2026-63845

A flaw was found in the Linux kernel, specifically within the AMD GPU's JPEG Joint Photographic Experts Group ring component. This vulnerability occurs because the JPEG v4.0 rings do not support 64-bit user fence writes. This can lead to the system rejecting command submissions that utilize user...

USN-8569-1: Linux kernel (HWE) vulnerabilities

It was discovered that some AMD processors did not properly clear data in the floating point divider unit during speculative execution. A local attacker could use this to expose sensitive information. CVE-2025-54505 It was discovered that some AMD Zen 2 processors did not properly isolate shared...

CVE-2026-63842

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/jpeg: set nouserfence for JPEG v5.0.0 ring JPEG rings do not support 64-bit user fence writes, reject CS submissions with user fences. cherry picked from commit 0f43893d3cd478fa57836697525b338817c9c23d...

EUVD-2026-45448

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/vce: Prevent partial address patches In the case that only one of lo/hi is valid, the patching could result in a bad address written to in FW...

PT-2026-61165

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the drm/amdgpu/jpeg component where JPEG v2.0 rings do not support 64-bit user fence writes. This leads to a failure to reject CS submissions that include user fences...

USN-8488-2: Linux kernel (Raspberry Pi) vulnerabilities

It was discovered that some AMD processors did not properly clear data in the floating point divider unit during speculative execution. A local attacker could use this to expose sensitive information. CVE-2025-54505 Several security issues were discovered in the Linux kernel. An attacker could...

The vulnerability of the `dc_allow_idle_optimizations_internal()` function in the `drivers/gpu/drm/amd/display/dc/core/dc.c` file of the Linux kernel’s Direct Rendering Infrastructure driver architecture allows a attacker to cause a service failure.

The vulnerability of the dcallowidleoptimizationsinternal function in the drivers/gpu/drm/amd/display/dc/core/dc.c file of the Linux kernel’s Direct Rendering Infrastructure driver is related to the assignment of a NULL pointer. Exploiting this vulnerability could allow an attacker to cause a...
