Descriptions

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]

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: drm/xe: Se corrige la toma de un bloqueo no válido en una cuña. Si el dispositivo realiza una cuña durante, por ejemplo, la carga de GuC, el envío aún no está habilitado y el estado ni siquiera se inicializa. Se protege la llamada a la cuña para que no haga nada en este caso. Corrige el siguiente problema: [] 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]
