| CVE-2026-3184 | 2 Linux, Redhat | 4 Util-linux, Enterprise Linux, Hummingbird and 1 more | 2026-04-08 | 3.7 Low |
| 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, potentially bypassing host-based Pluggable Authentication Modules (PAM) access control rules that rely on fully qualified domain names. This could lead to unauthorized access. | ||||
| CVE-2026-27456 | 1 Linux | 1 Util-linux | 2026-04-07 | 4.7 Medium |
| 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 with user privileges via fork() + setuid() + realpath(), but subsequently re-canonicalizes and opens it with root privileges (euid=0) without verifying that the path has not been replaced between both operations. Neither O_NOFOLLOW, nor inode comparison, nor post-open fstat() are employed. This allows a local unprivileged user to replace the source file with a symlink pointing to any root-owned file or device during the race window, causing the SUID binary to open and mount it as root. Exploitation requires an /etc/fstab entry with user,loop options whose path points to a directory where the attacker has write permission, and that /usr/bin/mount has the SUID bit set (the default configuration on virtually all Linux distributions). The impact is unauthorized read access to root-protected files and block devices, including backup images, disk volumes, and any file containing a valid filesystem. This issue has been patched in version 2.41.4. | ||||
| CVE-2011-1675 | 2 Linux, Redhat | 2 Util-linux, Enterprise Linux | 2025-04-11 | N/A |
| mount in util-linux 2.19 and earlier attempts to append to the /etc/mtab.tmp file without first checking whether resource limits would interfere, which allows local users to trigger corruption of the /etc/mtab file via a process with a small RLIMIT_FSIZE value, a related issue to CVE-2011-1089. | ||||
| CVE-2011-1676 | 1 Linux | 1 Util-linux | 2025-04-11 | N/A |
| mount in util-linux 2.19 and earlier does not remove the /etc/mtab.tmp file after a failed attempt to add a mount entry, which allows local users to trigger corruption of the /etc/mtab file via multiple invocations. | ||||
| CVE-2011-1677 | 2 Linux, Redhat | 2 Util-linux, Enterprise Linux | 2025-04-11 | N/A |
| mount in util-linux 2.19 and earlier does not remove the /etc/mtab~ lock file after a failed attempt to add a mount entry, which has unspecified impact and local attack vectors. | ||||
| CVE-2008-1926 | 2 Linux, Redhat | 2 Util-linux, Enterprise Linux | 2025-04-09 | N/A |
| Argument injection vulnerability in login (login-utils/login.c) in util-linux-ng 2.14 and earlier makes it easier for remote attackers to hide activities by modifying portions of log events, as demonstrated by appending an "addr=" statement to the login name, aka "audit log injection." | ||||
