Local information disclosure via unchecked buffer read
Published Apr 6, 2023 · Updated Feb 12, 2025
Out-of-bounds read in MediaTek power components on Android 11.0 through 13.0 allows local users to disclose information. The power component retains active debug code and reads beyond a buffer because the relevant bound is not checked. Exploitation requires System execution privileges but no user interaction, and the reported consequence is limited to local information disclosure.
