The vulnerability of the remove() function in the driver/gpu/drm/amd/amdgpu/amdgpu_gmc.c file of the Direct Rendering Infrastructure (DRI) AMD GPU kernel for the Linux operating system allows a attacker to cause a service failure.

The vulnerability of the remove function in the driver/gpu/drm/amd/amdgpu/amdgpugmc.c file of the Direct Rendering Infrastructure DRI driver for AMD GPU cores in the Linux operating system is related to pointer manipulation. Exploiting this vulnerability could allow an attacker to cause a service...

CVE-2026-74449

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix divide-by-zero in calculatemcachesetting on zero viewport If a plane reaches calculatemcachesetting with a zero-area viewport, calculatemcachesetting exits early with nummcaches == 0 and mvmpgwidth/height == ...

CVE-2026-74450

In the Linux kernel, the following vulnerability has been resolved: drm/amd/pm: fix pptable use-after-free amdgpudpmgetpptable returns a pointer to a driver-owned power table after dropping adev-pm.mutex. The sysfs path then copies from that pointer. A concurrent pptable write can replace and fre...

CVE-2026-74449

The CVE-2026-74449 issue affects the Linux kernel DRM/AMD display path. A zero-area viewport can lead calculate_mcache_setting to exit with num_mcaches == 0 and mvmpg_width/height == 0, causing a divide-by-zero panic (and potential num_mcaches underflow). The fix changes calculate_mcache_setting ...

PT-2026-72284

In the Linux kernel, the following vulnerability has been resolved: dma-fence: Make dma fence dedup array robust against 0-count input dma fence dedup array returns 1 when called with num fences == 0: the for-loop body never executes, j stays at 0, and the final return ++j yields 1. This...

CVE-2026-68447 drm/amdkfd: clamp v9 CRIU control stack checkpoint copy to BO size

In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: clamp v9 CRIU control stack checkpoint copy to BO size CRIU checkpoint copies the MQD control stack using cphqdcntlstacksize from hardware without bounding it to the allocated BO region. If the HW field is larger than...

CVE-2026-68430

CVE-2026-68430 affects the Linux kernel, specifically the DRM AMDGPU gfx8 path. The vulnerability arises from an unnecessary BUG_ON() that could crash the kernel; the fix is to drop this BUG_ON() check. The issue was resolved by cherry-picking the corresponding patch (commit 4d7c25208ca612b754f3b...

CVE-2026-68112

A flaw was found in the drm/amdgpu/gfx9.4.3 component of the Linux kernel. This vulnerability is due to the use of BUGON macros in error handling, which, when triggered by specific error conditions, could cause the kernel to crash. This could result in a Denial of Service DoS for the system...

CVE-2026-68276

A flaw was found in the Linux kernel's drm/amdgpu/gfx component. A local attacker could exploit a buffer overflow vulnerability in the cleaner shader's sysfs path. This occurs because the system incorrectly writes 256 double words dwords into a buffer allocated for only 16 dwords 64 bytes...

CVE-2026-68252

A flaw was found in the drm/amdgpu/sdma7.0 component of the Linux kernel. This vulnerability could lead to a kernel crash, resulting in a Denial of Service DoS. The issue was caused by an improper use of BUGON which has been replaced with WARNON to prevent system instability...
