CVE-2019-9475

Local network-data disclosure via permissive /proc/net access

Published Jun 11, 2021 · Updated Aug 4, 2024

Information disclosure in Android 10 allows local users to read kernel network data through improperly accessible /proc/net files. The SELinux policy fails to confine reads of /proc/net resources to their intended security domains, exposing connection-related kernel data. Execution from a local untrusted-app context is required; no user interaction or additional execution privileges are needed, and the reported impact is read-only disclosure.
