libsmkvextractor in Samsung Mobile devices has improper input validation that allows attackers to trigger a crash via a crafted file.
Vulnerability
An improper input validation check logic vulnerability exists in libsmkvextractor prior to the SMR Jun-2022 Release 1. This library is part of Samsung Mobile devices' multimedia framework. The flaw allows a crafted input file to bypass validation checks, leading to a crash. Affected versions include all Samsung Mobile firmware before the June 2022 security update [1].
Exploitation
An attacker needs to deliver a specially crafted file (e.g., a malformed video or multimedia container) to a device running an affected version. No authentication is required, but user interaction may be necessary if the file is opened via an application that triggers parsing by libsmkvextractor [1].
Impact
Successful exploitation causes a denial of service (crash) of the affected process. The impact is limited to temporary device instability or application termination; no remote code execution or data compromise has been disclosed [1].
Mitigation
Samsung released a fix in the SMR Jun-2022 Release 1 security update. Users should update their device firmware via the standard Samsung Security Update mechanism. No workaround is listed [1].
