CVE-2019-2056

Local RAM disclosure via shared cryptographic key

Published Apr 17, 2020 · Updated Aug 4, 2024

Information disclosure in the Android 10 Framework allows local users to read RAM through an improperly shared cryptographic key. The nonpublic Framework implementation reuses a cryptographic key in a way that exposes memory contents; Google has not published the affected function or data path. A local application with ordinary execution privileges can obtain sensitive data without user interaction, while integrity and availability remain unaffected.
