Summary

drm/xe/configfs: Free ctx_restore_mid_bb in release

Details

In the Linux kernel, the following vulnerability has been resolved:

drm/xe/configfs: Free ctxrestoremid_bb in release

ctxrestoremidbb memory is allocated in wabbstore(), but xeconfigdevicerelease() only frees ctxrestorepost_bb.

Free ctxrestoremid_bb[0].cs as well to avoid leaking the allocation when the configfs device is removed.
