Heap-based buffer overflow in Windows NTFS allows an unauthorized attacker to elevate privileges with a physical attack.
AnalysisAI
Privilege escalation via heap-based buffer overflow in the Windows NTFS filesystem driver affects a broad range of Windows 10, Windows 11, and Windows Server versions, requiring only physical access to the target device - no OS credentials needed. An attacker with hands-on access to the hardware can trigger a heap overflow in NTFS processing to gain elevated privileges, potentially achieving full system compromise (High C/I/A). …

Vulnerability AssessmentAI
| Exploitation | Exploitation unconditionally requires physical access to the target device - this is the primary and hardest prerequisite. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS base score of 6.8 is driven primarily downward by the AV:P (Physical) attack vector, which is the dominant risk-limiting factor. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with physical access to an unattended Windows workstation or server inserts a USB drive containing a crafted NTFS filesystem volume designed to trigger the heap buffer overflow in the Windows NTFS driver during volume mounting or directory traversal. The overflow corrupts adjacent heap memory, enabling the attacker to redirect execution flow and elevate from a low-privileged or unauthenticated session context to SYSTEM-level privileges. … |
| Remediation | Apply the vendor-released patch available from Microsoft via the Security Response Center advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2026-50668. … Detailed patch versions, workarounds, and compensating controls in full report. |
