CVE-2026-53144

Local kernel panic via null queue pointer

Published Jun 25, 2026 · Updated Jun 25, 2026

NULL pointer dereference in the Linux kernel allows local users to trigger a kernel panic through an AMD KFD debug-trap ioctl. When a nonzero queue count accompanies a null queue pointer, get_queue_ids returns NULL, its callers accept it as non-error, and q_array_invalidate dereferences it. Access to the KFD debug-trap ioctl and a crafted request are required; successful exploitation crashes the host without reported data disclosure or modification.
