Source: FIRST.org, updated on 23 September 2026.
The affected software is deployed exclusively in isolated environments with no internet connectivity and restricted external access. Exploitation of this vulnerability requires a user to open a specially crafted MKV file provided by an attacker. Since the system operates in a controlled network without exposure to untrusted sources, the likelihood of receiving and executing malicious media files is significantly reduced. Additionally, operational procedures can enforce the use of trusted media files only, further minimizing the risk.
