CVE-2026-93248: Linux kernel drm/xe GPU driver warning on kernel job timeout

CVE-2026-93248 · Severity: info · Published 2026-09-24

The Linux kernel's Xe GPU driver incorrectly generates a kernel warning when a graphics processor times out during teardown of an already-disabled device. This causes unnecessary kernel log tainting during normal device shutdown procedures, which can be mistaken for actual errors in monitoring systems.

Technologies: Linux kernel.

Technical details

A logic flaw in xe_guc_submit.c's guc_exec_queue_timedout_job() function causes it to treat expected timeouts as unexpected warnings when killed execution queues are being torn down on a wedged device. The timeout handler skips calling guc_submit_hint_wedged() for killed queues, leaving the 'wedged' flag false even though the device is already in a wedged state, triggering a spurious WARN macro.
