CVE-2023-35687

Local privilege escalation via MtpPropertyValue use after free

Published Sep 11, 2023 · Updated Sep 26, 2024

Android elevation of privilege in MtpPropertyValue affects Android 11, 12, 12L, and 13 and allows local users to gain elevated privileges through crafted media-transfer data. The MtpPropertyValue implementation in MtpProperty.h accesses an object after it has been freed, causing memory corruption during property handling. Exploitation requires local access but no additional execution privileges or user interaction, and can compromise confidentiality, integrity, and availability.
