CISA KEV Advisory
Microsoft Windows Kernel Privilege Escalation Vulnerability
The kernel in Microsoft Windows allows local users to gain privileges via a crafted application.
Apply updates per vendor instructions.
Risk Analysis
A vulnerability in the Microsoft Windows kernel allows local users to gain elevated privileges through a specially crafted application. This could allow an attacker to take full control of the affected system. The high EPSS score of 0.78880 indicates a high likelihood of exploitation, and its inclusion in CISA's KEV confirms active exploitation.
Active exploitation of this vulnerability has been observed in the wild, as confirmed by its presence in CISA's KEV. This vulnerability requires local access to the system for exploitation.
Ensure all Windows systems are fully patched with the latest security updates. Implement strong user access controls and restrict the execution of untrusted applications.
Technical Analysis
CVE-2016-0040 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-2016-0040 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.
