CVE-2023-4211Arm Mali driver — freed memory reachable again

The Arm graphics driver (GPU) lets an unprivileged user on the device drive memory operations that reach storage already released. Arm publishes the class of flaw; the fixed driver reaches phones only through the handset maker.

YOUR NEXT MOVE

Take the fixed Mali driver from Arm, or the handset maker's build carrying it. A device past its update window keeps this one permanently.
