Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · low confidence
Developing — this CVE was published recently and its authoritative NVD entry is still being established, so we're holding a technical summary until the source data settles rather than publish something unreliable. Re-checking after 2026-08-01.

Affected products & versions What the vendor confirmedThe version ranges the vendor confirmed as vulnerable. If your version sits inside a range here, treat yourself as exposed until you have upgraded.

Recommended fix High confidence

Upgrade to the Windows version-specific KB patches: Windows 10 1507 → 10.0.10240.20651, 1607 → 10.0.14393.6981, 1809 → 10.0.17763.5820, 21h2 → 10.0.19044.4412; Windows 11 21h2 → 10.0.22000.2960, 22h2 → 10.0.22621.3593, 23h2 → 10.0.22631.3593; Windows Server 2008 requires migration to supported OS

  1. Identify the current Windows version by running 'winver' or 'systeminfo' in Command Prompt

  3. For Windows 10 1507 systems: upgrade to version 10.0.10240.20651 or later
  4. For Windows 10 1607 systems: upgrade to version 10.0.14393.6981 or later
  5. For Windows 10 1809 systems: upgrade to version 10.0.17763.5820 or later
  6. For Windows 10 21h2 systems: upgrade to version 10.0.19044.4412 or later
