Technical summary

CVE-2024-53155 is an uninitialized value vulnerability in the ocfs2_file_read_iter() function of the OCFS2 (Oracle Cluster File System 2) Linux kernel module. The vulnerability exists in how the function handles certain read operations without proper initialization of values, potentially leading to information disclosure or undefined behavior. This CVE was included in CISA advisory ICSA-25-226-07 covering third-party components in Siemens SINEC OS, affecting industrial networking products including RUGGEDCOM RST2428P and SCALANCE XC-300/XR-300/XC-400/XR-500WG/XR-500 family devices. However, the advisory marks the impact as 'Misinformed,' suggesting the vulnerability's applicability to these products may be incorrect or requires clarification. The advisory has undergone four revisions, with the February 25, 2026 update removing multiple rejected CVEs and clarifying affected configurations. No CVSS score is assigned, and the vulnerability is not in the KEV catalog.
