CVE-2022-48456

Local denial of service via incorrect bounds check

Published Nov 1, 2023 · Updated Sep 12, 2024

An out-of-bounds write in the UNISOC camera driver on Android 11 through 13 allows local users to cause a local denial of service. The driver applies an incorrect bounds check before a write, allowing data to be written beyond the intended buffer; no file or function is public. Reaching the flaw requires System execution privileges, and the public record does not state whether the interruption is a hang, crash, or reboot.
