CVE-2024-26922

Unspecified impact via invalid AMDGPU mapping ranges

Published Apr 23, 2024 · Updated Aug 5, 2026

Improper input validation in the Linux kernel AMDGPU VM code allows local users to trigger unspecified impact through GPU mapping ioctls. The amdgpu_vm_bo_map, amdgpu_vm_bo_replace_map, and amdgpu_vm_bo_clear_mappings paths inconsistently accept unaligned, zero-length, overflowing, object-out-of-bounds, or maximum-PFN-exceeding ranges. Reachability requires local access to an AMDGPU DRM device node, and upstream has not published the resulting failure mode.
