Use after free in Windows Bind Filter Driver allows an authorized attacker to elevate privileges locally.
AnalysisAI
Privilege escalation in the Windows Bind Filter Driver (bindflt.sys) permits a low-privileged local attacker to gain SYSTEM-level access on Windows 11 and Windows Server 2025 by exploiting a race condition that triggers a use-after-free in kernel memory. Affected builds span Windows 11 24H2, 25H2, and 26H1, as well as Windows Server 2025 including Server Core installations; Microsoft has released patched builds via the MSRC update guide. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The attacker must have a low-privileged local authenticated session on the target Windows system (PR:L confirmed by CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H, score 7.0) accurately reflects a locally-triggered, high-complexity attack that nonetheless yields full CIA impact at the kernel level. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Apply the vendor-released patch via Windows Update or the Microsoft Update Catalog, targeting the following minimum fixed builds: Windows 11 24H2 and 25H2 - build 10.0.26100.9168 or 10.0.26200.9168 respectively; Windows 11 26H1 - build 10.0.28000.2704; Windows Server 2025 (full and Server Core) - build 10.0.26100.33296. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all Windows 11 systems (builds 24H2, 25H2, 26H1) and Windows Server 2025 installations, including Server Core deployments, to identify business-critical systems requiring priority remediation. …
