Lifecycle Timeline
4DescriptionCVE.org
Software installed and run as a non-privileged user may conduct improper GPU system calls to manipulate the lifetimes of synchronisation objects in the kernel, leading to read/write UAFs.
During workload submission involving a fence exported by the GPU driver, the reference count of the underlying synchronisation primitive is not properly incremented. This can be exploited, by destroying the exported fence and prematurely release the underlying primitive, resulting in a potential use-after-free condition.
AnalysisAI
Memory corruption and use-after-free in Imagination Technologies Graphics DDK allows local attackers to escalate privileges. The vulnerability stems from improper reference counting on synchronization primitives during fence export, enabling a low-privileged user to achieve kernel read/write and full system compromise. No active exploitation or public exploit is confirmed, and EPSS indicates low exploitation probability.
