CVE-2023-42679

Local service interrupt via unchecked GPU write

Published Dec 4, 2023 · Updated Aug 2, 2024

Out-of-bounds write in the UNISOC GPU driver allows local users with System privileges to interrupt affected Android devices. The GPU driver performs an out-of-range write because it omits a bounds check, but UNISOC has not disclosed the affected function or input field. Exploitation requires local System-level execution; UNISOC identifies denial of service but does not disclose whether the failure is a hang, crash, or reboot.
