Local information disclosure via unchecked keyInstall bounds
Published May 6, 2024 · Updated Aug 1, 2024
Out-of-bounds read in keyInstall on MediaTek chipsets running Android 12.0 through 14.0 allows local users to disclose memory. The keyInstall code reads beyond a valid buffer because it fails to check the supplied bounds before accessing data. Exploitation requires prior System privilege, needs no user interaction, and provides local information disclosure only.
