Untrusted pointer dereference in Microsoft Windows SCSI Class System File allows an unauthorized attacker to elevate privileges with a physical attack.
AnalysisAI
Privilege escalation via untrusted pointer dereference in the Windows SCSI Class System File affects a broad range of Windows 10, 11, and Windows Server releases, requiring physical access to trigger. An attacker with physical access to a target machine can connect a malicious SCSI device, causing the kernel-mode SCSI class driver to dereference an attacker-controlled pointer and elevate from unprivileged to full system (kernel) control. …

Vulnerability AssessmentAI
| Exploitation | Physical access to the target machine is the mandatory prerequisite - the CVSS AV:P vector is unambiguous. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Despite C:H/I:H/A:H impact ratings suggesting full system compromise, real-world risk is sharply curtailed by the AV:P (Physical) attack vector: exploitation mandates an adversary who can physically connect a malicious SCSI device to the target. … 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 addressing the fixed build thresholds listed above (e.g., 10.0.17763.9245 for Windows 10 1809/Server 2019, 10.0.26100.9445 for Windows 11 24H2, and equivalent builds per edition). … Detailed patch versions, workarounds, and compensating controls in full report. |
