CVE-2024-56785 Siemens CVE debrief

CVE-2024-56785 describes issues with PCIe port nodes for ls7a in the MIPS Loongson64 Device Tree Source (DTS). The vulnerability was originally published on 2025-08-12 and last modified on 2026-02-25. According to the source advisory, this CVE is marked as **Misinformed** in the threat assessment, indicating it does not represent a genuine security vulnerability requiring remediation. The advisory (ICSA-25-226-07) was republished by CISA on 2026-02-25 based on Siemens ProductCERT advisory SSA-355557. No CVSS score or severity has been assigned. The affected products listed in the source include Siemens RUGGEDCOM RST2428P, SCALANCE XC-300/XR-300/XC-400/XR-500WG/XR-500 family, and SCALANCE XCM-/XRM-/XCH-/XRH-300 family, though the threat categorization suggests these products are not actually vulnerable to this issue.

Who should care

Security teams managing Siemens industrial networking equipment (SCALANCE switches, RUGGEDCOM devices) and vulnerability management programs should be aware of this CVE to avoid wasting resources on false positive remediation efforts. Organizations using automated vulnerability scanning tools that may flag this CVE should implement documentation to properly classify and dismiss findings related to CVE-2024-56785. Asset owners in industrial control system (ICS) environments should focus defensive resources on other validated vulnerabilities in the same advisory rather than this misinformed entry.

Technical summary

CVE-2024-56785 pertains to Device Tree Source (DTS) configuration issues with PCIe port nodes for the Loongson64 ls7a platform in the MIPS architecture. The vulnerability description indicates problems with how PCIe ports are defined in the device tree, which could theoretically affect hardware initialization or resource allocation. However, the authoritative source advisory (ICSA-25-226-07) explicitly categorizes the impact of this CVE as 'Misinformed,' indicating that it does not constitute a genuine security vulnerability. The CVE was initially included in a list of rejected CVEs that were removed from the advisory in February 2026, then subsequently retained with the corrected classification. No CVSS vector, score, or severity rating has been assigned. The advisory covers multiple Siemens industrial networking products (RUGGEDCOM RST2428P, SCALANCE XC/XR/XCM/XRM/XCH/XRH families) but clarifies that these products are not actually affected by this particular issue.

Defensive priority

low

Recommended defensive actions

  • Verify that security monitoring and vulnerability management processes correctly classify CVE-2024-56785 as non-actionable based on the 'Misinformed' threat assessment in the source advisory.
  • Review internal vulnerability databases to ensure this CVE is not incorrectly flagged for remediation or patch deployment.
  • For Siemens SCALANCE and RUGGEDCOM devices, prioritize attention on other CVEs in advisory ICSA-25-226-07 that have valid threat classifications.
  • Maintain awareness that this CVE may appear in automated vulnerability scans due to its initial publication; establish documentation for security teams to quickly dismiss false positive findings.

Evidence notes

The source advisory ICSA-25-226-07 explicitly categorizes this CVE's impact as 'Misinformed' per the threats section. The CVE was included in a batch of rejected CVEs removed in revision 3 of the advisory (2026-02-24), then retained with the 'Misinformed' classification in the 2026-02-25 republication. No technical details of exploitability are provided in the source corpus.
