This vulnerability involves a Use After Free condition in the Arm Ltd Valhall GPU Kernel Driver, specifically in the Arm 5th Gen GPU Architecture Kernel Driver versions from r50p0 through r54p3 and r55p0. A local non-privileged user process can exploit this by performing valid GPU processing operations that access memory after it has been freed, which may result in undefined behavior or security issues related to memory safety.

The impact is limited to local non-privileged users who can execute GPU processing operations. Exploitation could lead to memory corruption or unauthorized access to freed memory regions within the GPU driver, potentially compromising system stability or confidentiality of data handled by the GPU driver. There is no indication of remote exploitation or privilege escalation beyond the local user context.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or workaround information is currently available. Users should monitor Arm Ltd advisories for updates and apply patches once released.
