CVE-2022-39132

Kernel denial of service via camera bounds check

Published Dec 6, 2022 · Updated Apr 24, 2025

Out-of-bounds write in Unisoc camera driver on Android 10, 11, or 12 allows local users to cause kernel denial of service. The driver writes beyond a camera-buffer boundary because a required bounds check is missing, corrupting kernel memory. Local users need low privileges and no user interaction; the documented consequence is a kernel service interruption without confidentiality or integrity impact.
