CVE-2025-38353 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/xe: Fix taking invalid lock on wedge If device wedges on e.g. GuC upload, the submission is not yet enabled and the state is not even initialized. Protect the wedge call so it does nothing in this case. It fixes the following splat: [] xe 0000:bf:00.0: [drm] device wedged, needs recovery [] ------------[ cut here ]------------ [] DEBUG_LOCKS_WARN_ON(lock->magic != lock) [] WARNING: CPU: 48 PID: 312 at kernel/locking/mutex.c:564 __mutex_lock+0x8a1/0xe60 ... [] RIP: 0010:__mutex_lock+0x8a1/0xe60 [] mutex_lock_nested+0x1b/0x30 [] xe_guc_submit_wedge+0x80/0x2b0 [xe]
A vulnerability in the Linux kernel's Direct Rendering Manager (DRM) subsystem, specifically within the Xe graphics driver, has been addressed. The issue arose when a device became unresponsive during Graphics Microcontroller (GuC) upload, leading to a warning about an invalid lock being taken. This occurred because the submission was not yet enabled and the device state was uninitialized. The vulnerability allowed the wedge call to improperly attempt recovery, causing a lock magic mismatch warning. The fix ensures that the wedge call is appropriately protected, preventing it from executing under these problematic conditions.
