CVE-2024-41015 Siemens CVE debrief

CVE-2024-41015 addresses a missing bounds check in the OCFS2 (Oracle Cluster File System version 2) Linux kernel module. The vulnerability exists in the ocfs2_check_dir_entry() function, which lacked proper validation to ensure that ocfs2_dir_entry structure members remain within valid memory boundaries. Without these sanity checks, malformed directory entries could potentially cause out-of-bounds memory access. The fix adds explicit bounds checking to validate that all members of the ocfs2_dir_entry structure do not extend beyond allocated memory regions. This vulnerability was published on August 12, 2025, and the advisory was subsequently modified on February 25, 2026, as part of CISA's republication based on Siemens ProductCERT advisory SSA-355557. The affected product identified in the source advisory is the Siemens RUGGEDCOM RST2428P (6GK6242-6PA00), though the threat assessment categorizes the impact as 'Misinformed' for the listed product IDs. No CVSS score or severity rating is available in the source data. Organizations should consult the Siemens ProductCERT advisory for specific patch availability and apply kernel updates that include the ocfs2 bounds checking fix when available.

Who should care

System administrators managing Linux systems with OCFS2 filesystems, security teams responsible for industrial control system infrastructure, Siemens RUGGEDCOM and SCALANCE product operators, and organizations running Oracle Cluster File System version 2 in production environments.

Technical summary

CVE-2024-41015 is a vulnerability in the OCFS2 (Oracle Cluster File System version 2) Linux kernel module. The ocfs2_check_dir_entry() function lacked proper bounds validation for ocfs2_dir_entry structures, potentially allowing directory entry members to reference memory outside valid regions. The remediation adds sanity checks to ensure all structure members remain within allocated memory boundaries. This is a defensive hardening fix that prevents potential memory safety issues when processing OCFS2 directory entries. The vulnerability affects systems using OCFS2, including certain Siemens industrial networking products that incorporate the vulnerable kernel component.

Defensive priority

Recommended defensive actions

  • Review Siemens ProductCERT advisory SSA-355557 for specific product impact and patch availability
  • Apply kernel updates containing the ocfs2 bounds checking fix when available for affected systems
  • Monitor CISA ICS advisories for updates to ICSA-25-226-07
  • Implement defense-in-depth strategies for industrial control systems per CISA recommended practices
  • Validate OCFS2 filesystem integrity on systems using Oracle Cluster File System version 2

Evidence notes

The source advisory (ICSA-25-226-07) indicates this CVE was included in a Siemens Third-Party Components in SINEC OS advisory. The threat category is marked as 'Misinformed' for product IDs CSAFPID-0006, CSAFPID-0002, and CSAFPID-0003. The advisory underwent multiple revisions, with the most recent update on February 25, 2026, removing several rejected CVEs and clarifying affected product configurations. The vulnerability description indicates this is a kernel-level fix for OCFS2 directory entry validation.
