CVE-2024-53181 Siemens CVE debrief

A vulnerability in the Linux kernel's User-Mode Linux (UML) vector driver could allow a local attacker to cause a denial of service condition. The issue stems from improper handling of driver data during release operations, where drvdata is not available when expected. This affects Siemens industrial networking products running SINEC OS, specifically the RUGGEDCOM RST2428P and SCALANCE switch families. The vulnerability requires local access and low privileges to exploit, with no impact to confidentiality or integrity, but high availability impact. Siemens has released updates to address this issue.

Who should care

Organizations operating Siemens RUGGEDCOM RST2428P switches or SCALANCE XC-300/XR-300/XC-400/XR-500WG/XR-500 and XCM-/XRM-/XCH-/XRH-300 family switches in industrial environments. Critical infrastructure operators, manufacturing facilities, and utility providers using these devices for network infrastructure should prioritize patching.

Technical summary

The vulnerability exists in the User-Mode Linux (UML) vector driver where driver data (drvdata) is not properly available during release operations. This can lead to a NULL pointer dereference or use-after-free condition, resulting in system crash or denial of service. The CVSS 3.1 base score of 5.5 reflects local attack vector, low attack complexity, low privileges required, and high availability impact with no confidentiality or integrity effects. Affected Siemens products incorporate this vulnerable kernel component in their SINEC OS firmware.

Defensive priority

Recommended defensive actions

  • Apply vendor-provided updates to V3.2 or later for affected RUGGEDCOM and SCALANCE products per Siemens ProductCERT guidance
  • For SCALANCE XC-300/XR-300/XC-400/XR-500WG/XR-500 family, consult Siemens support documentation for specific configuration guidance
  • Implement defense-in-depth strategies for industrial control systems per CISA recommended practices
  • Restrict local access to affected systems to authorized personnel only
  • Monitor for anomalous system behavior or unexpected reboots on affected devices
