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

drm/xe/configfs: Free ctxrestoremidbb in release

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

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

(cherry picked from commit a235e7d0098337c3f2d1e8f3610c719a589e115f)
