Name of the Vulnerable Software and Affected Versions McAfee File Lock versions 5.x

Description The issue is related to a stack-based buffer overflow in the McPvDrv.sys driver, which can cause a denial of service, resulting in a system crash. This occurs when a long vault GUID is passed in an ioctl call.

Recommendations For McAfee File Lock version 5.x, update the McPvDrv.sys driver to a version that fixes the buffer overflow issue. As a temporary workaround, consider restricting the length of vault GUIDs passed to the ioctl call to prevent the buffer overflow.
