Actively Exploited
CISA Known Exploited Vulnerabilities (KEV) Catalog
EPSS (Exploit Prediction Scoring System) estimates a 20.5% chance this CVE is exploited in the wild within the next 30 days — higher than 97% of all CVEs. It complements CVSS: a high EPSS on a mid-severity CVE can still be urgent.
A privilege escalation vulnerability exists when the Windows kernel fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode.
Description
The kernel-mode drivers in Microsoft Windows Vista SP2; Windows Server 2008 SP2 and R2 SP1; Windows 7 SP1; Windows 8.1; Windows Server 2012 Gold and R2; Windows RT 8.1; and Windows 10 Gold, 1511, and 1607 allow local users to gain privileges via a crafted application, aka "Win32k Elevation of Privilege Vulnerability," a different vulnerability than CVE-2016-3308, CVE-2016-3310, and CVE-2016-3311.
