In the Linux kernel, the following vulnerability has been resolved:
drm/xe/configfs: Free ctx_restore_mid_bb in release
ctx_restore_mid_bb memory is allocated in wa_bb_store(), but xe_config_device_release() only frees ctx_restore_post_bb.
Free ctx_restore_mid_bb[0].cs as well to avoid leaking the allocation when the configfs device is removed.
