Local information disclosure via unchecked RIL bounds
Published Mar 7, 2023 · Updated Mar 6, 2025
Out-of-bounds read in MediaTek RIL on Android 12.0 and 13.0 allows local users with System privileges to disclose process memory. The RIL component reads beyond a buffer boundary because it processes untrusted input without the required bounds check. Exploitation requires System execution privileges but no user interaction, and the reported consequence is limited to local information disclosure.
