Name of the Vulnerable Software and Affected Versions: FreeBSD versions 5.x

Description: The issue allows local users to read arbitrary kernel memory. This can be achieved through the syscons CONS SCRSHOT ioctl by using either negative coordinates or large coordinates.

Recommendations: For FreeBSD version 5.x, consider restricting access to the syscons CONS SCRSHOT ioctl until a patch is available. As a temporary workaround, avoid using the CONS SCRSHOT ioctl with negative or large coordinates to minimize the risk of exploitation.
