CVE-2026-93248

Estado: RecibidaSin puntuar—

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.

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)
