17
FAUCET Score

CVE-2015-7513 is a medium-severity vulnerability in the Linux kernel (before version 4.4) affecting KVM virtualization, specifically Canonical, Debian, Fedora, and Linux distributions. A guest OS user can trigger a denial of service (host OS crash) by manipulating the PIT counter values during state restoration, leading to a divide-by-zero error. The attack requires local access to the guest OS with low complexity and no user interaction. There is no evidence of active exploitation, publicly available exploit code, or significant community discussion surrounding this CVE.
