CVE-2022-39897

Kernel-address disclosure via logging API

Published Dec 8, 2022 · Updated Apr 23, 2025

Information disclosure in the Qualcomm kernel on selected Samsung Android 10 through 12 devices allows local users to read kernel addresses from logs. A kernel API exposes kernel address information through a log accessible to privileged local software; Samsung's patch removes that API. Exploitation requires local access with high privileges and is limited to address disclosure, with no reported write or service-interruption impact.
