CISA KEV Advisory

Microsoft Win32k Privilege Escalation Vulnerability

Added to KEV: 2022-03-28Federal patch deadline: 2022-04-18

Required Action (CISA)

Apply updates per vendor instructions.

Risk Analysis

This vulnerability in the win32k.sys kernel-mode drivers in Microsoft allows local users to gain privileges due to improper pointer initialization. With an EPSS score of 0.69169 and confirmed exploitation in CISA's KEV, this flaw presents a significant and urgent risk of privilege escalation.

This vulnerability is actively exploited in the wild. Exploitation requires local access to the system, allowing an attacker to elevate their privileges.

Recommended Action

Microsoft Windows users should apply all available security updates to patch the kernel-mode drivers. Implement strong access controls and monitor for suspicious activity to prevent local privilege escalation.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2013-3660 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

CISA has added CVE-2013-3660 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
