| CVE-2026-53614 | Hig | 7.0 | < 2.42.2-1.1 | 2.42.2-1.1 | Oct 14, 2026 | util-linux is a random collection of Linux utilities. In util-linux 2.39.1 through 2.41.4 and 2.42 through 2.42.1, the SUID `mount` utility reads the attacker-controlled `LIBMOUNT_FORCE_MOUNT2` environment variable with `getenv()`, allowing a local low-privileged user to force th | |

In util-linux 2.17 through 2.41.6 and 2.42 through 2.42.3, and in 2.42.4 when the legacy `mount(2)` path is used without `/proc`, restricted non-root `mount` requests validate an `/etc/fstab` target before the mount operation | |

In util-linux 2.39 through 2.41.4 and 2.42 through 2.42.1, the SUID `mount` utility's `hook_owner.c` post-mount hook performs path-based `chmod()` and `lchown()` operations on a previously validated mount target. A local low-p | |
| CVE-2026-76642 | Hig | 7.8 | < 2.42.3-1.1 | 2.42.3-1.1 | Sep 3, 2026 | util-linux versions through 2.41.5 and 2.42.2 fail to check mount helper exit status before running post-mount hooks, allowing unprivileged users to execute privileged operations on pre-existing filesystems. Attackers can exploit X-mount.idmap or X-mount.owner hooks to clone file | |
| CVE-2026-78410 | Hig | 7.8 | < 2.42.3-1.1 | 2.42.3-1.1 | Sep 2, 2026 | A flaw was found in util-linux. Restricted bind mounts take the source path from fstab but do not pin that source before the privileged mount. A local unprivileged user who can replace the authorized source or a writable ancestor can redirect SUID mount(8) to bind another host di | |
| CVE-2026-78409 | Hig | 7.0 | < 2.42.3-1.1 | 2.42.3-1.1 | Sep 2, 2026 | The X-mount.subdir option uses a detached-tree fast path on Linux 6.15 and later and passes the configured subdirectory to open_tree() with AT_SYMLINK_NOFOLLOW. That flag does not stop intermediate symlink traversal or keep resolution inside the newly mounted filesystem. A local | |
| CVE-2026-78408 | Hig | 7.9 | < 2.42.3-1.1 | 2.42.3-1.1 | Sep 2, 2026 | The nsenter --join-cgroup option opens the target cgroup.procs file as root and leaves that file descriptor open across later namespace and credential changes and across execve(). Because the kernel checks later cgroup migrations using the credentials from the original open, a pr | |

| CVE-2026-27456 | Med | 4.7 | < 2.42-1.1 | 2.42-1.1 | Apr 3, 2026 | util-linux is a random collection of Linux utilities. Prior to version 2.41.4, a TOCTOU (Time-of-Check-Time-of-Use) vulnerability has been identified in the SUID binary /usr/bin/mount from util-linux. The mount binary, when setting up loop devices, validates the source file path | |
| CVE-2026-3184 | Low | 3.7 | < 2.41.3-4.1 | 2.41.3-4.1 | Apr 3, 2026 | A flaw was found in util-linux. Improper hostname canonicalization in the `login(1)` utility, when invoked with the `-h` option, can modify the supplied remote hostname before setting `PAM_RHOST`. A remote attacker could exploit this by providing a specially crafted hostname, pot | |
| CVE-2025-14104 | Med | 6.1 | < 2.41.3-1.1 | 2.41.3-1.1 | Dec 5, 2025 | A flaw was found in util-linux. This vulnerability allows a heap buffer overread when processing 256-byte usernames, specifically within the `setpwnam()` function, affecting SUID (Set User ID) login-utils utilities writing to the password database. | |

| CVE-2016-5011 | Med | 4.6 | < 2.36.2-3.2 | 2.36.2-3.2 | Apr 11, 2017 | The parse_dos_extended function in partitions/dos.c in the libblkid library in util-linux allows physically proximate attackers to cause a denial of service (memory consumption) via a crafted MSDOS partition table with an extended partition boot record at zero offset. | |
| CVE-2014-9114 | Hig | 7.8 | < 2.28.2-2.1 | 2.28.2-2.1 | Mar 31, 2017 | Blkid in util-linux before 2.26rc-1 allows local users to execute arbitrary code. | |
