| 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-2020-21583 | Med | 0.37 | 6.7 | 0.01 | Aug 22, 2023 | An issue was discovered in hwclock.13-v2.27 allows attackers to gain escalated privlidges or execute arbitrary commands via the path parameter when setting the date. | ||

| 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-2026-3184 | Low | 0.24 | 3.7 | 0.00 | 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,… | ||

| 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-2017-2616 | Med | 0.00 | 5.5 | 0.00 | Jul 27, 2018 | A race condition was found in util-linux before 2.32.1 in the way su handled the management of child processes. A local authenticated attacker could use this flaw to kill other processes with root privileges under specific conditions. | ||
| 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. |
