Cyber Security News is a Dedicated News Platform For Cyber News, Cyber Attack News, Hacking News & Vulnerability Analysis. When enabled in “integrity” mode, it blocks runtime kernel modifications, while “confidentiality” mode prevents memory introspection tools from exposing sensitive data. Gurubaran is a co-founder of Cyber Security News and GBHackers On Security. The regression, first observed in December 2024, stems from a misconfigured kernel build process that inadvertently deactivated the CONFIG_SECURITY_LOCKDOWN_LSM_EARLY flag. The vulnerability carries a CVSSv3.1 score of 7.7 (High) due to its ability to compromise confidentiality, integrity, and availability under specific configurations. This vulnerability underscores the critical role of kernel-level security mechanisms in modern Linux distributions. System administrators should prioritize kernel updates and audit /boot/config-* files to confirm CONFIG_SECURITY_LOCKDOWN_LSM_EARLY=y is present. Ongoing monitoring and kernel integrity checks remain essential for enterprise deployments. Researchers uncovered nine critical vulnerabilities in NVIDIA’s CUDA Toolkit, a cornerstone software suite for GPU-accelerated computing. A vulnerable system returns [none] integrity confidentiality, indicating no active enforcement. He has 10+ years of experience as a Security Consultant, Editor, and Analyst in cybersecurity, technology, and communications. In affected Fedora kernels (≥6.12), the lockdown subsystem fails to initialize due to a missing lockdown= boot parameter.
