Name of the Vulnerable Software and Affected Versions Comodo Antivirus version 12.0.0.6870

Description A use-after-free flaw in the sandbox container implemented in cmdguard.sys can be triggered due to a race condition when handling IRP MJ CLEANUP requests in the minifilter for directory change notifications. This allows an attacker to cause a denial of service (BSOD) when an executable is run inside the container.

Recommendations For Comodo Antivirus version 12.0.0.6870, consider disabling the sandbox container feature until a patch is available to prevent potential denial of service attacks.
