Name of the Vulnerable Software and Affected Versions Microsoft Windows XP (affected versions not specified)

Description The issue concerns the process scheduler in the Microsoft Windows XP kernel, which does not utilize process statistics kept by the kernel. Instead, it performs scheduling based on CPU billing gathered from periodic process sampling ticks and gives preference to "interactive" processes that perform voluntary sleeps. This allows local users to cause a denial of service by consuming CPU resources.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
