Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fixed potential NULL pointer dereferences in dcn10setoutputtransferfunc. The stream pointer is used in dcn10setoutputtransferfunc before checking whether stream is NULL. The issue was fixed in:...

Astra Linux – Vulnerability in Linux 5.10

In the dplinksettingswrite function in the file drivers/gpu/drm/amd/display/amdgpudm/amdgpudmdebugfs.c in the Linux kernel, up to version 5.14.14, there is a vulnerability that allows for a heap-based buffer overflow by an attacker. This vulnerability arises because the attacker can write a strin...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fixed an out-of-bounds access in ‘dcn21linkencodercreate’. An issue was identified in the dcn21linkencodercreate function, where an out-of-bounds access could occur when the hpdsource index was used to reference...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fixed the use-after-free bug. This bug can be triggered by sending a single amdgpugemuserptrioctl command to the AMDGPU DRM driver on any ASICs with an invalid address and size. The bug was reported by Joonkyo Jung...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: drm/amd/display: fixed a double-free issue during the unloading of the amdgpu module Flexible endpoints use DIGs from available inflexible endpoints; therefore, only the encoders of inflexible links need to be freed. Otherwise...

CVE-2026-31766

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. A local user could exploit this vulnerability by providing a malformed doorbell offset during user queue creation. This lack of proper bounds checking allows the offset to exceed the allocated memory, potentially corrupting critical...

CVE-2026-31765

A flaw was found in the Linux kernel's AMDGPU driver. On systems configured with 64KB page sizes, a mismatch between the reserved trap area size and the allocated memory for the Kernel Fusion Driver KFD can lead to a kernel crash. A local user running specific applications, such as rocminfo or rc...

CVE-2026-31765

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Change AMDGPUVARESERVEDTRAPSIZE to 64KB Currently, AMDGPUVARESERVEDTRAPSIZE is hardcoded to 8KB, while KFDCWSRTBATMASIZE is defined as 2 PAGESIZE. On systems with 4K pages, both values match 8KB, so allocation and...

CVE-2026-31766

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: validate doorbelloffset in user queue creation amdgpuuserqgetdoorbellindex passes the user-provided doorbelloffset to amdgpudoorbellindexonbar without bounds checking. An arbitrarily large doorbelloffset can cause the...

CVE-2026-31766

The CVE-2026-31766 issue affects the Linux kernel AMDGPU driver: amdgpu_userq_get_doorbell_index() passes user-supplied doorbell_offset to amdgpu_doorbell_index_on_bar() without proper bounds checking. An arbitrarily large doorbell_offset can drive the computed doorbell index outside the allocate...

EUVD-2026-26579

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: validate doorbelloffset in user queue creation amdgpuuserqgetdoorbellindex passes the user-provided doorbelloffset to amdgpudoorbellindexonbar without bounds checking. An arbitrarily large doorbelloffset can cause the...

EUVD-2026-26578

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: Change AMDGPUVARESERVEDTRAPSIZE to 64KB Currently, AMDGPUVARESERVEDTRAPSIZE is hardcoded to 8KB, while KFDCWSRTBATMASIZE is defined as 2 PAGESIZE. On systems with 4K pages, both values match 8KB, so allocation and...

CVE-2026-31765

Summary: CVE-2026-31765 affects the Linux kernel AMDGPU driver. A mismatch between the reserved trap area (AMDGPU_VA_RESERVED_TRAP_SIZE) and the allocated KFD GPU memory on systems with 64KB pages can cause a kernel crash, including a NULL pointer dereference, when running certain GPU tests (e.g....
