MediumCVSS 6.8 · v4.0—Proof of concept Fix available

Noroxi assessment

Priority: Monitor (action score 27/100)

  • Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.18% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: MSI Dragon Center 2.0.148.0.

Low priority for now. Upgrade to MSI Dragon Center 2.0.148.0 or later.
