Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/xe/configfs: Free ctx_restore_mid_bb in release<br /> <br /> ctx_restore_mid_bb memory is allocated in wa_bb_store(), but<br /> xe_config_device_release() only frees ctx_restore_post_bb.<br /> <br /> Free ctx_restore_mid_bb[0].cs as well to avoid leaking the allocation<br /> when the configfs device is removed.<br /> <br /> (cherry picked from commit a235e7d0098337c3f2d1e8f3610c719a589e115f)
