Name of the Vulnerable Software and Affected Versions:
Windows Win32K versions prior to the fixed version
Description:
The issue is a heap-based buffer overflow in Windows Win32K - GRFX, allowing an unauthorized attacker to execute code locally. This enables an attacker to gain SYSTEM-level access via improper memory handling. The vulnerability can be exploited by remote attackers to execute arbitrary code and affect the system.
Recommendations:
For versions prior to the fixed version, update to the latest version to resolve the issue.
As a temporary workaround, consider restricting access to the GRFX component until a patch is applied.
Avoid using the vulnerable Windows Win32K - GRFX functionality until the issue is resolved.
