Instead of throwing a warning and allowing access to such file, treat them as regular files. The Linux kernel CVE team has assigned CVE-2025-21830 to this issue. Affected and fixed versions =========================== Issue introduced in 5.13 with commit cb2c7d1a1776057c9a1f48ed1250d85e94d4850d and fixed in 6.1.129 with commit 7d6121228959ddf44a4b9b6a177384ac7854e2f9 Issue introduced in 5.13 with commit cb2c7d1a1776057c9a1f48ed1250d85e94d4850d and fixed in 6.6.76 with commit 39bb3d56f1c351e76bb18895d0e73796e653d5c1 Issue introduced in 5.13 with commit cb2c7d1a1776057c9a1f48ed1250d85e94d4850d and fixed in 6.12.13 with commit 2569e65d2eb6ac1afe6cb6dfae476afee8b6771a Issue introduced in 5.13 with commit cb2c7d1a1776057c9a1f48ed1250d85e94d4850d and fixed in 6.13.2 with commit 0fde195a373ab1267e60baa9e1a703a97e7464cd Issue introduced in 5.13 with commit cb2c7d1a1776057c9a1f48ed1250d85e94d4850d and fixed in 6.14-rc1 with commit 49440290a0935f428a1e43a5ac8dc275a647ff80 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2025-21830 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: security/landlock/fs.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/7d6121228959ddf44a4b9b6a177384ac7854e2f9 https://git.kernel.org/stable/c/39bb3d56f1c351e76bb18895d0e73796e653d5c1 https://git.kernel.org/stable/c/2569e65d2eb6ac1afe6cb6dfae476afee8b6771a https://git.kernel.org/stable/c/0fde195a373ab1267e60baa9e1a703a97e7464cd https://git.kernel.org/stable/c/49440290a0935f428a1e43a5ac8dc275a647ff80
