Windows Graphics Kernel: Information disclosure via untrusted pointer dereference
Summary
A flaw in the Windows Graphics Kernel allows an untrusted pointer dereference (CWE-822) that can disclose information. An attacker needs local access and low privileges, and the attack complexity is high. Successful exploitation exposes confidential data only; integrity and availability are not affected. The flaw is not remotely exploitable by itself.
Affected
- Windows 10 Version 1809 and Windows Server 2019 (including Server Core): builds before 10.0.17763.9487
- Windows 10 Version 21H2: builds before 10.0.19044.7846
- Windows 10 Version 22H2: builds before 10.0.19045.7846
- Windows 11 Version 23H2: builds before 10.0.22631.7711
- Windows 11 Version 24H2 and 25H2: builds before 10.0.26100.9974 and 10.0.26200.9974
- Windows 11 Version 26H1: builds before 10.0.28000.3501
- Windows 11 Version 26H2: builds before 10.0.26300.9974
- Windows Server 2022: builds before 10.0.20348.5870
- Windows Server 2025 (including Server Core): builds before 10.0.26100.33822
The build ranges are taken from the CVE record. Confirm them on MSRC.
Fixed in
Fixed in the November 2026 security updates for the affected Windows versions. The fixed builds are the first builds listed above as not affected. Exact KB numbers are not confirmed; check the MSRC update guide and Microsoft's update history.
Workaround
Unknown. No vendor workaround was found for this CVE. Installing the November 2026 update is the mitigation.
Exploitation
- CISA SSVC: exploitation none, automatable no, technical impact partial.
- Rapid7 rates it 'Exploitation Less Likely' and not publicly disclosed.
- No public proof of concept or exploit was found.
- Information disclosure flaws are rarely exploited on their own, but are often used as part of a longer chain.
Our recommendation
- Install the November 2026 security update on all affected Windows 10, Windows 11 and Windows Server systems, and prioritise terminal servers and shared workstations.
- Check the support status of Windows 10 Version 1809 and Windows Server 2019 before relying on the patch; plan an upgrade if they are out of support.
- Limit local logon to trusted users and monitor for suspicious local activity.
- Plan testing and reboots, as the November 2026 release is large.
- Confirm the exact fixed builds and KB numbers on MSRC.
