Name of the Vulnerable Software and Affected Versions: Zillya! Antivirus version 3.0.2230.0

Description: The issue is related to the driver file zef.sys, which does not validate input values from IOCtl 0x9C402424, allowing local users to cause a denial of service (BSOD) or possibly have other unspecified impacts.

Recommendations: For Zillya! Antivirus version 3.0.2230.0, consider updating to a newer version that addresses the input validation issue in the zef.sys driver file. As a temporary workaround, restrict access to the IOCtl 0x9C402424 to minimize the risk of exploitation.
