CVE-2026-68276

The CVE affects the Linux kernel driver path drm/amdgpu/gfx. The cleaner shader sysfs path allocated a 16-dword (64-byte) IB but incorrectly filled (align_mask + 1) dwords; with align_mask 0xff, the loop wrote 256 dwords into a 64-byte buffer, causing a kernel page fault. The fix is to fill 16 dw...
