CVE-2023-52349

Local service crash via unchecked RIL write

Published Apr 8, 2024 · Updated Mar 28, 2025

Out-of-bounds write in the UNISOC RIL service on affected chipsets running Android 12 through Android 14 allows local users to cause denial of service. The RIL service processes an undisclosed input without a required bounds check and writes beyond the destination buffer. Exploitation requires local access with System execution privileges and can interrupt the RIL service; no broader impact is documented.
