CVE-2014-0254

Status: ModifiedHigh (7.8)—

The IPv6 implementation in Microsoft Windows 8, Windows Server 2012, and Windows RT does not properly validate packets, which allows remote attackers to cause a denial of service (system hang) via crafted ICMPv6 Router Advertisement packets, aka "TCP/IP Version 6 (IPv6) Denial of Service Vulnerability."

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
