Technical details
A race condition exists in the destruction path of hardware performance counters buffers, where non-atomic reference counter decrements allow use-after-free (UAF) reads and writes to kernel heap memory. Non-privileged users can trigger this via malformed GPU system calls, gaining unauthorized access to freed kernel objects on the GPU driver's heap.
