CVE-2020-0075

Local information disclosure via unchecked key bounds

Published Apr 17, 2020 · Updated Aug 4, 2024

Out-of-bounds read in Android kernel's FPC Iris TrustZone app allows local users to disclose information with System privileges. The set_shared_key function reads beyond an intended buffer because it fails to validate bounds on supplied data. Exploitation requires System execution privileges, needs no user interaction, and is limited to local information disclosure.
