CVE-2020-10845

Memory corruption via unsynchronized MTP handler race

Published Mar 24, 2020 · Updated Aug 4, 2024

Use-after-free in the MTP handler on Samsung mobile devices running Android 8.x, 9.0, or 10.0 allows physically proximate attackers to corrupt memory. Missing synchronization permits concurrent MTP handler operations to race, leaving one operation to access an object after another frees it. Exploitation requires direct access to the device's MTP interface and winning the race; Samsung does not specify whether the corruption causes a crash or code execution.
