CVE-2022-42530

Local information disclosure via unchecked buffer bounds

Published Dec 16, 2022 · Updated Apr 17, 2025

Out-of-bounds read in Google Pixel firmware allows local users with System privileges to disclose memory without user interaction. The unpublished firmware code reads beyond a buffer because it does not verify bounds before access. Exploitation requires System execution privileges and exposes memory contents locally; no integrity or availability impact is reported.
