The reference count changes made as part of the CVE-2023-33951 and
CVE-2023-33952 fixes exposed a use-after-free flaw in the way memory
objects were handled when they were being used to store a surface. When
running inside a VMware guest with 3D acceleration enabled, a local,
unprivileged user could potentially use this flaw to escalate their
privileges.
Author | Note |

Priority reason: Local user with access to drm devices (video or render groups) can escalate privileges. |
