CVE-2024-20088

Local information disclosure via unchecked KeyInstall read

Published Sep 2, 2024 · Updated Mar 13, 2025

Out-of-bounds read in MediaTek KeyInstall on affected Android 12.0 through 14.0 chipsets allows local users to disclose information. KeyInstall reads past a buffer boundary because it does not validate the relevant bounds before accessing memory. Exploitation requires System execution privileges, needs no user interaction, and is limited to disclosure with no reported integrity or availability impact.
