System crash via unchecked devcoredump pointer
Published Jul 29, 2024 · Updated May 11, 2026
NULL pointer dereference in the Linux kernel 6.8 through 6.9.7 allows local users to crash the system through Intel Xe devcoredump handling. In xe_devcoredump, the code derives snapshot and device pointers from the coredump object before checking whether that object is NULL. Reachability requires local low-privilege access and an Intel Xe graphics path that produces a missing coredump object; the resulting NULL dereference interrupts the host.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
