CVE-2020-0077

Local information disclosure via unchecked enrollment bounds

Published Apr 17, 2020 · Updated Aug 4, 2024

Out-of-bounds read in the FPC Iris TZ App on Android kernel devices allows local users with System privileges to disclose memory. The authorize_enroll routine reads beyond an input buffer because it fails to validate the enrollment data bounds before accessing memory. Exploitation requires local System execution privileges but no user interaction, and the documented consequence is information disclosure only.
