CVE-2022-20172

Local information disclosure via unchecked service binding

Published Jun 15, 2022 · Updated Aug 3, 2024

Information disclosure in the Google Pixel Android kernel allows local users to read protected data through the Telephony service. ShannonRcsService.onbind exposes protected data because it binds callers without performing the required permission check. Exploitation requires local low-privileged code on the device, needs no user interaction, and is limited to confidentiality loss.
