Security readout for executives and security teams

Plain-English summary

CVE-2022-38767 is a denial-of-service issue in Wind River VxWorks 6.9 and 7. A specially crafted packet sent by a RADIUS server during IP RADIUS access may disrupt availability. It matters most where VxWorks-based systems support critical operations and depend on RADIUS authentication paths.

Executive priority

Treat as high priority for operational or safety-sensitive environments using VxWorks with RADIUS. The issue affects availability, not data theft, but outage impact can be significant in embedded and industrial systems. Prioritize asset confirmation and vendor remediation tracking.

Technical view

The CVE describes a network-reachable, low-complexity availability flaw during the IP RADIUS access procedure in VxWorks 6.9 and 7. CVSS 3.1 is 7.5 with no privileges or user interaction required, but the reported impact is availability only, not confidentiality or integrity.

Likely exposure

Exposure is likely limited to systems running Wind River VxWorks 6.9 or 7 that use the affected IP RADIUS access procedure. The provided bundle does not include reliable CPEs, device models, or a complete downstream OEM affected-products list.

Exploitation context

The bundle does not show CISA KEV listing or public active exploitation. The CVE states a crafted packet sent by a RADIUS server may cause denial of service, but no exploit maturity, proof-of-concept status, or attack prevalence is provided.

Researcher notes

Evidence is sparse: the CVE bundle lacks CWE, CPEs, detailed affected products, and named fixes. Analysis should stay tied to Wind River VxWorks 6.9 and 7 plus RADIUS access behavior until vendor or OEM advisories provide more specificity.

Mitigation direction

  • Check Wind River guidance for affected builds and available fixes.
  • Ask device OEMs whether their VxWorks-based products include this vulnerable code path.
  • Restrict RADIUS communication to trusted servers and management networks.
  • Monitor affected systems for authentication-related crashes or unexplained availability loss.
  • Track Siemens SSA-726834 if Siemens products are in scope.

Validation and detection

  • Inventory systems using Wind River VxWorks 6.9 or 7.
  • Confirm whether IP RADIUS access is enabled or reachable.
  • Map network paths between devices and RADIUS servers.
  • Review vendor advisories for exact fixed versions or OEM updates.
  • Check operational logs for denial-of-service symptoms during RADIUS activity.
