CriticalCVSS 9.8 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Plan (action score 42/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 8.4% (FIRST EPSS); higher than 95.1% of all records.
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: spice (Debian:12) 0.12.6-4.1; spice (Debian:8) 0.12.5-1+deb8u3; spice (openSUSE:Tumbleweed) 0.12.8-2.1.

Add it to your regular patch cycle. Upgrade to spice (Debian:12) 0.12.6-4.1; spice (Debian:8) 0.12.5-1+deb8u3; spice (openSUSE:Tumbleweed) 0.12.8-2.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The smartcard interaction in SPICE allows remote attackers to cause a denial of service (QEMU-KVM process crash) or possibly execute arbitrary code via vectors related to connecting to a guest VM, which triggers a heap-based buffer overflow.
