CVE-2024-53158 Siemens CVE debrief

CVE-2024-53158 is a medium-severity array underflow vulnerability in the Qualcomm GENI Serial Engine (geni-se) driver within the Linux kernel. The flaw exists in the geni_se_clk_tbl_get() function, where a loop condition intended to detect unchanged frequency values from clk_round_rate() is evaluated on the first iteration. This causes an out-of-bounds read before the start of the these->clk_perf_tbl[] array, potentially leading to information disclosure or system instability. The vulnerability was published on 2025-08-12 and last modified on 2026-02-25. Siemens has identified affected products in its industrial networking portfolio, including RUGGEDCOM RST2428P and SCALANCE switch families, as this vulnerability affects third-party Linux kernel components used in SINEC OS. The CVSS 3.1 vector (AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:H) indicates local attack vector with low attack complexity, requiring low privileges but no user interaction, with high availability impact. CISA and Siemens recommend updating affected devices to version 3.2 or later where available.

Who should care

Organizations operating Siemens RUGGEDCOM RST2428P, SCALANCE XC-300/XR-300/XC-400/XR-500WG/XR-500, or SCALANCE XCM-/XRM-/XCH-/XRH-300 industrial Ethernet switches in critical infrastructure environments. System administrators responsible for OT/ICS network security and patch management should prioritize firmware updates where available.

Technical summary

The geni_se_clk_tbl_get() function in drivers/soc/qcom/geni-se.c contains a logic error where a loop termination check comparing current and previous frequency values from clk_round_rate() executes on the first iteration. With no valid previous value established, this causes an array index underflow when accessing these->clk_perf_tbl[-1]. The vulnerability requires local access with low privileges and can result in information disclosure (C:L) and high availability impact (A:H). Affected Siemens products incorporate vulnerable Linux kernel versions in SINEC OS firmware.

Defensive priority
