CVE-2017-0263

Microsoft Win32k privilege escalation vulnerability allows attackers to escalate privileges via kernel-mode driver memory handling failures.

This vulnerability enables privilege escalation by exploiting improper memory handling in the Windows kernel-mode driver, allowing attackers to gain elevated access without remote code execution. DIB organizations must ensure all Windows systems are patched against this actively exploited vulnerability to prevent unauthorized access and maintain compliance with security requirements.

Shame score — Privilege escalation vulnerabilities in core Windows components are highly dangerous and were actively exploited in the wild, indicating severe negligence in patch management and security hardening.
