Local service interruption via incorrect GPU bounds check
Published Dec 4, 2023 · Updated Aug 2, 2024
Out-of-bounds write in Unisoc GPU drivers on Android 11 through 13 allows local users with System privileges to interrupt device service. The GPU driver applies an incorrect bounds check before a memory write, permitting the write beyond its intended boundary. Exploitation requires local access and System privileges; the vendor reports denial of service but does not identify whether the failure is a hang, crash, or reboot.
