Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/xe/client: add missing bo locking in show_meminfo()<br /> <br /> bo_meminfo() wants to inspect bo state like tt and the ttm resource,<br /> however this state can change at any point leading to stuff like NPD and<br /> UAF, if the bo lock is not held. Grab the bo lock when calling<br /> bo_meminfo(), ensuring we drop any spinlocks first. In the case of<br /> object_idr we now also need to hold a ref.<br /> <br /> v2 (MattB)<br /> - Also add xe_bo_assert_held()<br /> <br /> (cherry picked from commit 4f63d712fa104c3ebefcb289d1e733e86d8698c7)
