Local information disclosure via unchecked FLV bounds
Published Oct 25, 2021 · Updated Aug 3, 2024
An out-of-bounds read in MediaTek's flv extractor on Android 10.0 and 11.0 allows local users to disclose data via crafted FLV input. The extractor processes attacker-controlled FLV data without a required bounds check and reads beyond the intended buffer. No additional execution privileges or user interaction are required, and the reported consequence is limited to local information disclosure.
