CVE-2022-30719

Local crash via unchecked buffer length

Published Jun 7, 2022 · Updated Aug 3, 2024

Improper input validation in libsmkvextractor on Samsung Mobile Devices Q(10), R(11), and S(12) allows local users to trigger a crash. The library fails to validate a buffer length before processing input, allowing malformed data to reach the crash condition. Exploitation requires low-privileged local access and high-complexity conditions; Samsung has not disclosed the input format or affected entry point.
