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

Description The issue is related to the Windows kernel's improper handling of objects in memory, allowing an attacker to potentially run arbitrary code in kernel mode. This could enable the attacker to install programs, view, change, or delete data, or create new accounts with full user rights. To exploit this, an attacker would first need to log on to the system and then run a specially crafted application to take control of the affected system.

Recommendations To resolve the issue, apply the update that corrects how the Windows kernel handles objects in memory. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
