CVE-2024-38080: Windows Hyper-V Elevation of Privilege Vulnerability

HighCVSS 7.8 · v3.1KEVWeaponized Fix available

Noroxi assessment

Priority: This week (action score 63/100)

  • CISA has confirmed exploitation in the wild (Jul 9, 2024). Remediation deadline for US federal agencies: Jul 30, 2024.
  • Probability of exploitation in the next 30 days: 7% (FIRST EPSS); higher than 94.2% of all records.
  • 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: Windows 11 version 21H2 for ARM64-based Systems 10.0.22000.3079; Windows 11 version 21H2 for x64-based Systems 10.0.22000.3079; Windows 11 Version 22H2 for ARM64-based Systems 10.0.22621.3880.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Don’t wait for the next maintenance window. Upgrade to Windows 11 version 21H2 for ARM64-based Systems 10.0.22000.3079; Windows 11 version 21H2 for x64-based Systems 10.0.22000.3079; Windows 11 Version 22H2 for ARM64-based Systems 10.0.22621.3880 or later.

Actively exploited in the wild

CISA added this to its Known Exploited Vulnerabilities catalog on Jul 9, 2024. That signals real attacks, not theory.

Remediation deadline for US federal agencies: Jul 30, 2024.
