In the Linux kernel, the following vulnerability has been resolved:
drm/xe/eustall: Fix drm_dev_put called before stream disable in close
In xe_eu_stall_stream_close(), drm_dev_put() is called before the
stream is disabled and its resources are freed. If this drops the
last reference, the device structures could be freed while the
subsequent cleanup code still accesses them, leading to a
use-after-free.
Fix this by moving drm_dev_put() after all device accesses are
complete. This matches the ordering in xe_oa_release().
