CVE-2025-1272
HighSummary
Tryb lockdown jądra Linuxa dla wersji jądra od 6.12 wzwyż w systemie Fedora Linux ma wyłączony tryb lockdown bez żadnego ostrzeżenia. Może to umożliwić atakującemu dostęp do wrażliwych informacji, takich jak mapowania pamięci jądra, porty I/O, BPF i kprobes.
Risk Assessment
Ta podatność może prowadzić do załadowania niepodpisanych modułów, co umożliwia wykonanie nieufnego kodu i łamanie ochrony Secure Boot. Dotyczy to wyłącznie systemu Fedora Linux.
Recommendation
Zaleca się aktualizację jądra do najnowszej wersji, która przywraca tryb lockdown oraz monitorowanie systemu pod kątem nieautoryzowanych modułów.

Original NVD description (English source)
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.
