CVE-2023-52536

System-privileged service interruption via missing bounds check

Published Apr 8, 2024 · Updated Mar 26, 2025

Out-of-bounds read in Unisoc faceid service on affected Android 12 through Android 14 chipsets allows local users to interrupt the service. The service reads beyond a buffer boundary because it processes input without checking the relevant bound. Exploitation requires local access and System execution privileges; the public bulletin does not distinguish a crash from another interruption mode.
