FAUCET Score

CVE-2014-3647 describes a denial-of-service vulnerability in the KVM subsystem of the Linux kernel (through version 3.17.2), impacting various distributions including Canonical, Debian, and Red Hat. This flaw, residing in arch/x86/kvm/emulate.c, allows a guest OS user to crash the guest operating system by manipulating RIP changes with a crafted application. Rated as Medium severity (CVSS 5.5), the vulnerability requires local access to the guest OS and user interaction (running a crafted application) to achieve a high impact denial of service.

Community discussion and media coverage for this CVE are minimal, indicating a low level of public attention.
