CVE-2022-38672

Kernel denial of service via missing bounds check

Published Oct 14, 2022 · Updated May 15, 2025

Stack-based buffer overflow in Unisoc face detect driver on Android 10–12 allows local users to cause kernel denial of service. The driver writes beyond a stack buffer because input bounds are not checked before face-detection processing. Triggering the flaw requires local access to the affected device and can interrupt kernel operation without established confidentiality or integrity impact.
