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-2026-68276
In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu/gfx: fix cleaner shader IB buffer overflow The cleaner shader sysfs path allocates a 16-dword 64 byte IB but incorrectly fills alignmask + 1 dwords. On GFX rings alignmask is 0xff, so the loop wrote 256 dwords into a...
