CVE-2012-2551 is a critical denial-of-service vulnerability affecting the Kerberos server in Microsoft Windows 7 and Windows Server 2008 R2. An unauthenticated remote attacker can trigger a NULL pointer dereference and system reboot by sending a specially crafted session request. With a CVSS score of 5.0 and a FAUCET Risk Score of 97/100, this vulnerability poses a significant risk due to its low attack complexity and potential for system disruption. While there is no evidence of active exploitation, nor publicly available exploit code or significant community discussion, its high EPSS score suggests a non-trivial likelihood of future exploitation.
