CVE-2012-2137

22
FAUCET Score

CVE-2012-2137 is a buffer overflow vulnerability in the KVM subsystem of the Linux kernel before version 3.2.24, affecting various Linux distributions including Canonical Ubuntu and generic Linux kernels. This flaw allows local attackers to cause a denial of service (system crash) and potentially execute arbitrary code due to improper handling of Message Signaled Interrupts (MSI) and IRQ routing entries. With a CVSS score of 6.9, it has a high severity, requiring local access and medium attack complexity to achieve complete confidentiality, integrity, and availability impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
