Buffer over-read in Windows Overlay Filter allows an authorized attacker to disclose information locally.
AnalysisAI
Buffer over-read (CWE-126) in the Windows Overlay Filter (WofFilter) kernel driver enables local authenticated attackers with standard user privileges to disclose kernel memory contents under high-complexity conditions. The vulnerability spans a broad range of supported Windows 10, Windows 11, and Windows Server releases from build 1607 through 26H1, all patched via Microsoft's update cycle. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an authenticated local user account (PR:L) - the description explicitly states 'authorized attacker.' The high attack complexity (AC:H) indicates that exploitation is not straightforward; specific file system state, timing, or IOCTL parameter conditions must be met, making reliable exploitation substantially harder than a simple function call. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N accurately characterises a medium-severity local information disclosure: attack vector is local, complexity is high, and low user privileges are required, constraining exploitability to attackers who already have an interactive or remote session on the target host. … 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 Microsoft security updates corresponding to the installed Windows version: Windows Server 2016 and Windows 10 1607 should be updated to build 10.0.14393.9512 or later; Windows Server 2019, Windows 10 1809 should reach 10.0.17763.9245 or later; Windows Server 2022 should reach 10.0.20348.5622 or later; Windows Server 2025 and Windows 11 24H2 should reach 10.0.26100.33438/9445 or later; Windows 11 23H2 should reach 10.0.22631.7582 or later; Windows 11 25H2 should reach 10.0.26200.9445 or later; Windows 11 26H1 should reach 10.0.28000.2954 or later. … Detailed patch versions, workarounds, and compensating controls in full report. |
