CVE-2026-68445 drm/vc4: Prevent shader BO mappings from becoming writable

In the Linux kernel, the following vulnerability has been resolved: drm/vc4: Prevent shader BO mappings from becoming writable vc4gemobjectmmap rejects a writable mapping of a validated shader BO, but leaves VMMAYWRITE set. Userspace can map the BO read-only and then turn it writable with mprotec...

CVE-2026-68445

CVE-2026-68445 (Linux kernel, drm/vc4) fixes a local breach where a validated shader BO could be mapped read-only and then upgraded to writable via mprotect(), bypassing the validator. The issue stems from vc4_gem_object_mmap() leaving VM_MAYWRITE set on the read-only path, allowing userspace to ...

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...
