Out-of-bounds read in Windows Services for NFS ONCRPC XDR Driver allows an unauthorized attacker to deny service over a network.
AnalysisAI
Out-of-bounds read in the Windows Services for NFS ONCRPC XDR Driver enables unauthenticated remote attackers to crash the affected Windows system, causing a denial-of-service condition. The flaw resides in the kernel-mode driver that processes ONC RPC (Open Network Computing Remote Procedure Call) External Data Representation (XDR) packets, meaning a specially crafted network request can trigger a memory read beyond intended buffer boundaries - most likely a kernel panic (Blue Screen of Death). …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | The Windows Services for NFS role (specifically the 'Server for NFS' component) must be installed and running on the target system - this is an optional Windows role not present in default Windows installations. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H (7.5 High) accurately reflects the attack profile: the exploit is fully unauthenticated and network-reachable with no complexity barrier, but impact is limited to availability (A:H) with no confidentiality or integrity compromise. … 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 cumulative security updates for the relevant Windows version published by Microsoft, which bring each affected build above the patched version thresholds listed in the affected-versions data (e.g., Windows Server 2025 to 10.0.26100.33438 or later, Windows 11 24H2 to 10.0.26100.9445 or later). … Detailed patch versions, workarounds, and compensating controls in full report. |
