An issue was discovered in the utcp package before 0.0.6 for OCaml. Out-of-order segment reassembly allows remote denial of service.
AnalysisAI
Remote denial of service in the utcp OCaml TCP userspace library before version 0.0.6 is possible via crafted out-of-order TCP segment sequences that expose a flaw in the segment reassembly logic. Unauthenticated network attackers can exploit this against any service built on the affected library, causing complete availability loss. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | No special conditions beyond network access to a service using the utcp OCaml library - the CVSS vector is AV:N/AC:L/PR:N/UI:N, indicating remote unauthenticated exploitation against any utcp-backed service. … 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 reflects a realistic network-reachable DoS requiring no authentication and no special conditions, which aligns with the description of a remote reassembly flaw. … 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 | Upgrade the utcp OCaml package to version 0.0.6 or later, which resolves the out-of-order segment reassembly flaw. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
