Linux GPU Driver NULL Pointer Dereference

A NULL pointer dereference in the AMD GPU Linux kernel driver can allow a local user to crash the system, causing denial of service. The driver does not validate an internal reference during a graphics memory clear operation under certain compute-processing conditions. AMD lists Radeon Software for Linux 26.13 and Linux GPU Driver 31.40 as mitigations for the applicable products. Mitigations for affected embedded products are planned for October 2026; Radeon PRO V-series users should contact AMD. See AMD-SB-6034 for product-specific guidance.
