Technical details
The vulnerability is a use-after-free (CWE-416) in the GPU DDK kernel module where improper reference counting management allows software running as a non-privileged user to conduct unsupported GPU system calls. When resources are freed prematurely while still referenced, subsequent access to the released memory corrupts valid kernel data structures, potentially enabling further exploitation on systems where the compiler runs with elevated privileges.
