CVE-2022-20236Network attack vector

System crash or privilege escalation via out-of-bounds access

Published Jul 13, 2022 · Updated Aug 3, 2024

Out-of-bounds access in the UNISOC GPU driver on Android SoC allows attackers to crash the system or elevate privileges. The record identifies the DRM driver as the affected locus but does not disclose which operation permits memory access beyond a valid buffer. NVD models unauthenticated network reachability, while the public advisory does not identify the input path or state which reported consequence results.
