An issue in Unistal Systems Pvt. Ltd.’s Protogent 360 v2.0.0.4 permits a local user to invoke the internal function sub_13828, causing the antivirus service to become unresponsive or terminate unexpectedly. The resulting denial of service disables real‑time protection, allowing malware to run unchecked while the service is in a failed state. The flaw does not grant code execution or privilege escalation, but it disrupts the availability of the security product.

The product affected is Protogent 360 v2.0.0.4 from Unistal Systems Pvt. Ltd. No other vendors or versions are listed as impacted.

The CVSS score of 5.5 indicates a medium severity, and the EPSS score of less than 1% indicates low probability of public exploitation. Because the flaw requires local access, an attacker must already have physical or console access to the target machine. The vulnerability is not listed in CISA KEV, implying no known active exploitation. When triggered, the denial of service could allow other malicious processes to run unchecked while the antivirus is unavailable, but it does not grant further privileges or remote attack capabilities.
