Who should care

Organizations operating Siemens SCALANCE XC-300/XR-300/XC-400/XR-500WG/XR-500 family switches, SCALANCE XCM-/XRM-/XCH-/XRH-300 family devices, or RUGGEDCOM RST2428P industrial Ethernet switches running SINEC OS. OT security teams managing industrial network infrastructure, asset owners in critical infrastructure sectors utilizing Siemens networking equipment, and vulnerability management programs tracking third-party component security in industrial products.

Technical summary

CVE-2024-41087 describes a double-free condition in the Linux kernel's ATA library core (libata-core). The vulnerability occurs when error handling paths in the ATA subsystem may trigger multiple deallocation operations on the same memory object. This class of memory management flaw can lead to kernel memory corruption, potential denial of service, or privilege escalation in affected systems. The vulnerability affects Siemens industrial networking products utilizing SINEC OS, which incorporates the Linux kernel. Siemens' security assessment indicates the impact classification of 'Misinformed' suggests the CVE may have been incorrectly associated with affected product configurations, and organizations should verify actual exposure through the vendor's latest advisory guidance.

Defensive priority
