CVE-2024-26702 Siemens CVE debrief

A boundary check vulnerability in the Linux kernel's RM3100 magnetometer driver (iio: magnetometer: rm3100) was resolved by adding validation for values read from RM3100_REG_TMRC. The vulnerability involves insufficient boundary checking of register values that could lead to undefined behavior. Siemens has assessed this CVE as 'Misinformed' for affected industrial networking products including the RUGGEDCOM RST2428P and SCALANCE X-family devices, indicating the vulnerability does not actually affect these products as initially reported. The issue was originally published on August 12, 2025, with subsequent advisory updates through February 25, 2026, correcting product impact assessments.

Who should care

Organizations operating Siemens industrial networking equipment (RUGGEDCOM RST2428P, SCALANCE X-family) should verify their exposure assessment; Linux kernel maintainers and embedded systems developers using the RM3100 magnetometer driver should ensure boundary checks are implemented

Technical summary

The vulnerability exists in the Linux kernel's Industrial I/O (IIO) subsystem, specifically the RM3100 magnetometer driver. The fix adds boundary checking for values read from the RM3100_REG_TMRC register. Without proper bounds validation, register values could potentially cause out-of-bounds access or other undefined behavior. The RM3100 is a 3-axis magnetometer used in various sensing applications. Siemens has determined this vulnerability does not actually affect their reported product lines (RUGGEDCOM RST2428P, SCALANCE XC-300/XR-300/XC-400/XR-500WG/XR-500 family, SCALANCE XCM-/XRM-/XCH-/XRH-300 family), classifying the reported impact as 'Misinformed' in their security advisory.
