CVE-2024-41041 Siemens CVE debrief

A race condition vulnerability exists in the Linux kernel's UDP networking stack. The flaw, described as a 'small race window' in UDP packet processing, could potentially allow an attacker to cause unexpected behavior or denial of service conditions. The vulnerability affects Siemens industrial networking products running SINEC OS, specifically the RUGGEDCOM RST2428P switch and SCALANCE X family switches (XC-300/XR-300/XC-400/XR-500WG/XR-500 and XCM-/XRM-/XCH-/XRH-300 families). The CVSS 7.8 HIGH severity rating indicates significant risk to affected industrial control systems. CISA published this advisory on August 12, 2025, with subsequent updates through February 25, 2026, including corrections to affected product lists and clarifications on impacted configurations.

Who should care

Organizations operating Siemens RUGGEDCOM RST2428P switches or SCALANCE X family industrial Ethernet switches in critical infrastructure, manufacturing, or utility environments. Security teams responsible for OT/ICS network security should prioritize monitoring vendor patch releases.

Technical summary

The vulnerability resides in the Linux kernel's UDP implementation where a small race window exists during packet processing. This race condition could be triggered under specific timing conditions, potentially leading to memory corruption, use-after-free scenarios, or denial of service. The flaw affects Siemens industrial networking equipment that incorporates the vulnerable kernel code within SINEC OS. The 'Misinformed' impact classification in the source advisory suggests the actual security impact may differ from initial assessments, warranting close attention to vendor updates.

Defensive priority

HIGH

Recommended defensive actions

  • Review Siemens ProductCERT advisory SSA-355557 for detailed product-specific guidance and patch availability
  • Apply vendor-provided firmware updates for affected RUGGEDCOM and SCALANCE switch families as they become available
  • Implement network segmentation to limit exposure of industrial control system devices
  • Monitor CISA ICS advisories for additional updates to affected product configurations
  • Follow CISA recommended practices for industrial control systems defense in depth
