CriticalCVSS 9.8 · v3.0—No exploit Fix available

Noroxi assessment

Priority: Plan (action score 41/100)

  • 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: 5.6% (FIRST EPSS); higher than 93% 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: libxcursor (Debian:12) 1:1.1.15-1; libxcursor (Debian:8) 1:1.1.14-1+deb8u2; drm-utils (Red Hat:enterprise_linux:7::client) 0:2.4.91-3.el7.

Add it to your regular patch cycle. Upgrade to libxcursor (Debian:12) 1:1.1.15-1; libxcursor (Debian:8) 1:1.1.14-1+deb8u2; drm-utils (Red Hat:enterprise_linux:7::client) 0:2.4.91-3.el7 or later.
