CVE-2023-52883

Kernel crash via unchecked AMD GPU resource pointer

Published Jun 20, 2024 · Updated May 11, 2026

NULL pointer dereference in AMD GPU virtual-memory updates in Linux 6.4 through 6.5.8 allows local users to crash the kernel. The amdgpu_vm_bo_update function reads abo->tbo.resource->mem_type without first verifying that the resource pointer is non-NULL. Reachability requires the affected AMD GPU path and, under SUSE's assessment, high local privileges; the reported consequence is availability loss only.
