CVE-2022-20340

Website activity disclosure via missing SELinux permission

Published Aug 11, 2022 · Updated Aug 3, 2024

Information disclosure in Android 13 SELinux policy allows local users to infer websites opened in a browser without user interaction. The policy omits a permission check that should prevent an unprivileged local process from observing browser-related activity. A local low-privileged process is required, and the disclosed information is limited to which websites are opened.
