CVE-2022-47351

Local denial of service via camera-driver over-read

Published Aug 7, 2023 · Updated Oct 17, 2024

Out-of-bounds read in the UNISOC chipset camera driver on Android 11–13 allows local users to interrupt device service. The camera driver reads beyond a buffer boundary because it omits a bounds check before the relevant memory access. Exploitation requires System execution privileges, and the public record limits the consequence to local denial of service without identifying a crash, hang, or reboot.
