CVE-2026-69425: Windows NTFS Tampering Vulnerability

Noroxi assessment

Priority: Monitor (action score 18/100)

  • 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: 0.28% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: Windows 11 Version 23H2 for ARM64-based Systems 10.0.22631.7582; Windows 11 Version 23H2 for x64-based Systems 10.0.22631.7582; Windows 11 Version 24H2 for ARM64-based Systems 10.0.26100.9445.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Windows 11 Version 23H2 for ARM64-based Systems 10.0.22631.7582; Windows 11 Version 23H2 for x64-based Systems 10.0.22631.7582; Windows 11 Version 24H2 for ARM64-based Systems 10.0.26100.9445 or later.
