    CVE-2025-1272 (GCVE-0-2025-1272)

    Vulnerability from nvd – Published: 2026-02-18 20:29 – Updated: 2026-02-26 16:18
    VLAI
    Title
    Kernel: secure boot does not automatically enable kernel lockdown
    Summary
    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.

    CVE-2022-3675 (GCVE-0-2022-3675)

    Vulnerability from nvd – Published: 2022-11-03 17:25 – Updated: 2025-05-02 18:53
    VLAI
    Summary
    Fedora CoreOS supports setting a GRUB bootloader password using a Butane config. When this feature is enabled, GRUB requires a password to access the GRUB command-line, modify kernel command-line arguments, or boot non-default OSTree deployments. Recent Fedora CoreOS releases have a misconfiguration which allows booting non-default OSTree deployments without entering a password. This allows someone with access to the GRUB menu to boot into an older version of Fedora CoreOS, reverting any security fixes that have recently been applied to the machine. A password is still required to modify kernel command-line arguments and to access the GRUB command line.

    CVE-2025-1272 (GCVE-0-2025-1272)

    Vulnerability from cvelistv5 – Published: 2026-02-18 20:29 – Updated: 2026-02-26 16:18
    VLAI
    Title
    Kernel: secure boot does not automatically enable kernel lockdown
    Summary
    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.

    CVE-2022-3675 (GCVE-0-2022-3675)

    Vulnerability from cvelistv5 – Published: 2022-11-03 17:25 – Updated: 2025-05-02 18:53
    VLAI
    Summary
    Fedora CoreOS supports setting a GRUB bootloader password using a Butane config. When this feature is enabled, GRUB requires a password to access the GRUB command-line, modify kernel command-line arguments, or boot non-default OSTree deployments. Recent Fedora CoreOS releases have a misconfiguration which allows booting non-default OSTree deployments without entering a password. This allows someone with access to the GRUB menu to boot into an older version of Fedora CoreOS, reverting any security fixes that have recently been applied to the machine. A password is still required to modify kernel command-line arguments and to access the GRUB command line.
