Windows Wireless Networking: Elevation of privilege via use-after-free
Summary
A use-after-free flaw in the Windows Wireless Networking component allows an authorized local user to elevate privileges. Exploitation requires a logon on the machine and winning a race condition, so it is a follow-on step after an initial compromise rather than an internet-facing entry point. Microsoft reports no public disclosure and no exploitation, and the CVSS v3.1 base score is 7.0 (High).

Fixed in
- Install the Windows security updates released on November 10, 2026 (builds listed in the MSRC Security Update Guide).
- Fixed builds per the CVE record: 10.0.14393.9688, 10.0.17763.9487, 10.0.19044.7846, 10.0.19045.7846, 10.0.22631.7711, 10.0.26100.9974, 10.0.26200.9974, 10.0.28000.3501, 10.0.26300.9974, 10.0.20348.5870.
- KB numbers per build: Unknown. Verify in the MSRC table.
Workaround
Unknown. No vendor workaround has been identified; patching is the available fix.
Exploitation
- Microsoft: not publicly disclosed and not exploited.
- CVE record exploit maturity: Unproven.
- CISA SSVC: Exploitation none; not automatable.
- Attack requires winning a race condition and a local logon.
- No public proof-of-concept or KEV listing found at the time of research.
Our recommendation
- Apply the November 10, 2026 cumulative updates to all affected Windows 10, 11 and Server systems and verify build numbers afterwards.
- Prioritise servers, terminal or RDS hosts and shared or multi-user workstations, where untrusted local users are the highest risk.
- Restrict local logon rights and keep standard-user accounts on shared devices.
- Check whether CVE-2026-69517, which has an identical title, is a duplicate or a related entry.
- Re-check MSRC and CISA KEV for changes in exploitation status.
