AI-suggested
1. 2. If you cannot patch yet, restrict access to systems running affected Fedora versions by enforcing strict privilege separation and limiting local administrative access. 3. Employ additional host-based security controls such as Mandatory Access Control (e.g., SELinux) to limit kernel interface access. 4. Disable or restrict loading of kernel modules where possible, and monitor kernel module loading events for suspicious activity. 5. Use hardware-based security features like TPM and Secure Boot in conjunction with system integrity monitoring to detect unauthorized kernel modifications. 6. Conduct regular audits of privileged user activities and kernel module usage to detect potential exploitation attempts. 7. Consider temporary migration to unaffected Fedora versions or alternative Linux distributions if feasible until a patch is available.
Description
The Linux Kernel lockdown mode for kernel versions starting on 6.12 and above for Fedora Linux has the lockdown mode disabled without any warning. This may allow an attacker to gain access to sensitive information such kernel memory mappings, I/O ports, BPF and kprobes. Additionally unsigned modules can be loaded, leading to execution of untrusted code breaking breaking any Secure Boot protection. This vulnerability affects only Fedora Linux.
