Detailsinfo

A vulnerability classified as problematic has been found in Linux Kernel up to 7.2.5. Affected is the function guc_exec_queue_timedout_job of the file drivers/gpu/drm/xe/xe_guc_submit.c of the component drm/xe. The manipulation with an unknown input leads to a information disclosure vulnerability. CWE is classifying the issue as CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. This is going to have an impact on confidentiality. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: drm/xe: don't WARN on kernel job timeout when device already wedged igt@xe_wedged@wedged-at-any-timeout wedges the device in mode 2 (UPON_ANY_HANG_NO_RESET) and then rebinds the driver. During unbind, a GSC proxy kernel submission can still time out; with the device wedged and the GuC CT stopped it can never complete, so its kernel job times out. Tile0: GT1: Kernel-submitted job timed out WARNING: drivers/gpu/drm/xe/xe_guc_submit.c:... at guc_exec_queue_timedout_job() Workqueue: gt-ordered-wq drm_sched_job_timedout Killed queues skip guc_submit_hint_wedged(), leaving 'wedged' false even though the device is already wedged. The timeout handler then treats the kernel queue timeout as unexpected and taints the kernel. Honour an already-wedged device even for killed queues so the expected teardown timeout no longer trips the WARN. (cherry picked from commit a1c1dbd0f047bb05de6aaf6abe9103031179bf19)

The advisory is shared for download at git.kernel.org. This vulnerability is traded as CVE-2026-93248 since 09/17/2026. The exploitability is told to be easy. The attack needs to be approached locally. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1592.
