Technical details
An unprivileged user can cause improper release of memory resources in the kernel mode layer of the GPU display driver, resulting in a use-after-free condition where stale memory mappings remain accessible after the underlying memory is reused. This vulnerability requires local access to trigger and can result in arbitrary code execution, privilege escalation, or information disclosure depending on the attacker's exploitation strategy. The vulnerability is in the kernel driver component and affects unpatched versions.
