Local information disclosure via WLAN out-of-bounds read
Published Aug 7, 2023 · Updated Oct 28, 2024
Out-of-bounds read in MediaTek WLAN service on Android 12.0 and 13.0 allows local users to disclose information without interaction. The service improperly validates WLAN input before reading beyond the intended buffer, exposing adjacent memory. Exploitation requires System execution privileges, and the reported impact is limited to information disclosure.
