Memory disclosure via unchecked Wi-Fi driver read
Published Aug 17, 2021 · Updated Aug 3, 2024
An out-of-bounds read in MediaTek Wi-Fi drivers for Android 8.1 through 11 allows physically proximate attackers to disclose memory. The driver processes attacker-controlled wireless input without a required bounds check and reads beyond the intended buffer. No privileges or user interaction are required, but the attacker must be within wireless range; the disclosed memory contents are not specified.
