CVE-2017-5931 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. Integer overflow in hw/virtio/virtio-crypto.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (QEMU process crash) or possibly execute arbitrary code on the host via a crafted virtio-crypto request, which triggers a heap-based buffer overflow.. EPSS estimates a 0.53% chance of exploitation in the next 30 days.
