Local information disclosure via unchecked WLAN bounds
Published Jun 6, 2023 · Updated Jan 8, 2025
Out-of-bounds read in MediaTek WLAN on Android 13.0 and Yocto 3.1, 3.3, and 4.0 allows local users to read memory. The WLAN component reads beyond the intended buffer because it processes input without the required bounds check; MediaTek has not named the affected function or field. Exploitation requires System execution privileges but no user interaction, limiting the reported consequence to local confidentiality loss.
