Heap-based buffer overflow in Windows NTFS allows an authorized attacker to execute code locally.
AnalysisAI
Heap-based buffer overflow in the Windows NTFS filesystem driver allows a locally authenticated, low-privileged attacker to execute arbitrary code, most likely escalating to SYSTEM-level privileges. The vulnerability (CWE-122) affects an extraordinarily wide range of Microsoft Windows releases from Server 2012 through Server 2025 and Windows 10/11 across all current feature releases, making the aggregate exposed population very large. …

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires a low-privileged local account on the target Windows system (CVSS PR:L, AV:L) - any authenticated user capable of performing standard filesystem operations on an NTFS volume meets this bar. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 7.8 (High) with vector AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H accurately characterizes the local privilege escalation primitive: any low-privileged authenticated user, with no user interaction from another account and no special configuration required, can achieve full C/I/A compromise of the affected 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 update for CVE-2026-69709 via Windows Update, WSUS, or Microsoft Update Catalog, targeting the fixed build for each respective Windows version: Server 2016 and Windows 10 1607 - build 10.0.14393.9512; Server 2019 and Windows 10 1809 - build 10.0.17763.9245; Windows 10 21H2 - build 10.0.19044.7725; Windows 10 22H2 - build 10.0.19045.7725; Server 2022 - build 10.0.20348.5622; Server 2025 and Windows 11 24H2 - build 10.0.26100.9445 (Server 2025 patched up to 10.0.26100.33438); Windows 11 23H2 - build 10.0.22631.7582; Windows 11 25H2 - build 10.0.26200.9445; Windows 11 26H1 - build 10.0.28000.2954; Server 2012 - build 6.2.9200.26349; Server 2012 R2 - build 6.3.9600.23397. … Detailed patch versions, workarounds, and compensating controls in full report. |
