| CVE-2015-5224 | Cri | 0.57 | 9.8 | 0.05 | Aug 23, 2017 | The mkostemp function in login-utils in util-linux when used incorrectly allows remote attackers to cause file name collision and possibly other attacks. | ||
| CVE-2025-14104 | Med | 0.40 | 6.1 | 0.00 | 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-2026-13595 | Med | 0.37 | 6.8 | 0.00 | Jun 29, 2026 | A flaw was found in the libblkid library of util-linux. During nested partition probing, the BSD, Minix, Solaris x86, and UnixWare partition probers cache a raw pointer to a parent partition entry in a dynamically allocated array. When subsequent partition additions cause the… | ||
| CVE-2022-0563 | Med | 0.36 | 5.5 | 0.00 | Feb 21, 2022 | A flaw was found in the util-linux chfn and chsh utilities when compiled with Readline support. The Readline library uses an "INPUTRC" environment variable to get a path to the library config file. When the library cannot parse the specified file, it prints an error message… | ||
| CVE-2026-27456 | Med | 0.24 | 4.7 | 0.00 | 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-2024-28085 | Low | 0.22 | 3.3 | 0.02 | Mar 27, 2024 | wall in util-linux through 2.40, often installed with setgid tty permissions, allows escape sequences to be sent to other users' terminals through argv.

| CVE-2021-3995 | Med | 0.00 | 5.5 | 0.01 | Aug 23, 2022 | A logic error was found in the libmount library of util-linux in the function that allows an unprivileged user to unmount a FUSE filesystem. This flaw allows an unprivileged local attacker to unmount FUSE filesystems that belong to certain other users who have a UID that is a… | ||
| CVE-2021-37600 | Med | 0.00 | 5.5 | 0.01 | Jul 30, 2021 | An integer overflow in util-linux through 2.37.1 can potentially cause a buffer overflow if an attacker were able to use system resources in a way that leads to a large number in the /proc/sysvipc/sem file. NOTE: this is unexploitable in GNU C Library environments, and possibly… | ||
| CVE-2018-7738 | Hig | 0.00 | 7.8 | 0.00 | Mar 7, 2018 | In util-linux before 2.32-rc1, bash-completion/umount allows local users to gain privileges by embedding shell commands in a mountpoint name, which is mishandled during a umount command (within Bash) by a different user, as demonstrated by logging in as root and entering umount… | ||
| CVE-2015-5218 | 0.00 | — | 0.01 | Nov 9, 2015 | Buffer overflow in text-utils/colcrt.c in colcrt in util-linux before 2.27 allows local users to cause a denial of service (crash) via a crafted file, related to the page global variable. | |||

| CVE-2011-1677 | 0.00 | — | 0.00 | Apr 10, 2011 | 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-2011-1676 | 0.00 | — | 0.00 | Apr 10, 2011 | 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-2011-1675 | 0.00 | — | 0.00 | Apr 10, 2011 | 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… | |||
| CVE-2008-1926 | 0.00 | — | 0.04 | Apr 24, 2008 | 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… | |||
| CVE-2007-5191 | 0.00 | — | 0.00 | Oct 4, 2007 | mount and umount in util-linux and loop-aes-utils call the setuid and setgid functions in the wrong order and do not check the return values, which might allow attackers to gain privileges via helpers such as mount.nfs. | |||
| CVE-2006-7108 | 0.00 | — | 0.00 | Mar 4, 2007 | login in util-linux-2.12a skips pam_acct_mgmt and chauth_tok when authentication is skipped, such as when a Kerberos krlogin session has been established, which might allow users to bypass intended access policies that would be enforced by pam_acct_mgmt and chauth_tok. | |||
| CVE-2005-2876 | 0.00 | — | 0.00 | Sep 13, 2005 | umount in util-linux 2.8 to 2.12q, 2.13-pre1, and 2.13-pre2, and other packages such as loop-aes-utils, allows local users with unmount permissions to gain privileges via the -r (remount) option, which causes the file system to be remounted with just the read-only flag, which… | |||
| CVE-2004-0080 | 0.00 | — | 0.03 | Mar 3, 2004 | The login program in util-linux 2.11 and earlier uses a pointer after it has been freed and reallocated, which could cause login to leak sensitive data. |
