CVE-2024-49902 Siemens CVE debrief

CVE-2024-49902 describes a vulnerability in the jfs filesystem component related to the Qualcomm MSM GPU driver. The issue involves assigning msm_gpu->pdev earlier in the initialization process to prevent null pointer dereferences in msm_gpu_cleanup. The vulnerability was published on August 12, 2025, and last modified on February 25, 2026. Siemens has identified this CVE as affecting their RUGGEDCOM RST2428P (6GK6242-6PA00) product, though the source advisory marks the impact assessment as 'Misinformed' for the affected product IDs. The CVE appears to originate from the Linux kernel's jfs filesystem and MSM GPU driver interaction, where improper initialization ordering could lead to null pointer dereference conditions during cleanup operations. No CVSS score or severity rating is currently available in the source data. Organizations should consult the Siemens ProductCERT advisory for specific patch availability and applicability to their deployed systems.

Who should care

Organizations operating Siemens RUGGEDCOM RST2428P (6GK6242-6PA00) industrial networking equipment, industrial control system operators using SINEC OS with third-party Linux kernel components, and security teams responsible for OT/ICS infrastructure patch management.

Technical summary

The vulnerability exists in the jfs filesystem component's interaction with the Qualcomm MSM GPU driver. The root cause is improper initialization ordering where msm_gpu->pdev is not assigned early enough in the initialization process, potentially leading to null pointer dereferences during msm_gpu_cleanup operations. The fix involves assigning msm_gpu->pdev earlier in the initialization sequence to ensure proper cleanup handling.
