Microsoft Windows Graphics Kernel: Information disclosure via uninitialized resource
Summary
The Windows Graphics Kernel, the kernel-mode graphics component of Microsoft Windows, uses a resource that has not been initialized (CWE-908). A locally authorized attacker can read information that the kernel discloses. Exploitation requires local access with low privileges and high complexity. Only confidentiality is affected, and no exploitation or public proof of concept is known.

Fixed in
- Install the Microsoft security update from November 2026 (the cumulative update for each affected version).
- Minimum 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: Unknown. Take them from the MSRC advisory or Windows Update.
Workaround
Unknown. Microsoft lists no workaround; applying the update is the fix.
Exploitation
- Microsoft CISA SSVC data: exploitation none, automatable no, technical impact partial.
- Not known to be exploited in the wild, and no public proof of concept was found.
- Not listed in the CISA KEV catalogue according to the sources reviewed; the catalogue was not checked directly.
Our recommendation
- Install the November 2026 security update on all affected Windows 10, Windows 11 and Windows Server systems, prioritising multi-user systems, terminal servers and RDS hosts.
- Check whether Windows 10 1607 or 1809 hosts are still in use and verify their support status.
- Monitor for unusual local activity on shared systems. No separate mitigation is required once patched.
