| CVE-2026-27456 | 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.

| CVE-2026-3184 | 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. | [email protected] | 3.7 | 0.44% | 2026-04-03 | 2026-06-17 |
| CVE-2024-28085 | 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. (Specifically, escape sequences received from stdin are blocked, but escape sequences received from argv are not blocked.) There may be plausible scenarios where this leads to account takeover. | [email protected] | 3.3 | 2.24% | 2024-03-27 | 2026-06-17 |
| CVE-2020-21583 | 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. | [email protected] | 6.7 | 0.52% | 2023-08-22 | 2026-06-17 |
| CVE-2021-3996 | 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 a local user on a vulnerable system to unmount other users' filesystems that are either world-writable themselves (like /tmp) or mounted in a world-writable directory. An attacker may use this flaw to cause a denial of service to applications that use the affected filesystems. | [email protected] | 5.5 | 0.63% | 2022-08-23 | 2026-06-17 |
| CVE-2021-3995 | 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 prefix of the UID of the attacker in its string form. An attacker may use this flaw to cause a denial of service to applications that use the affected filesystems. | [email protected] | 5.5 | 0.63% | 2022-08-23 | 2026-06-17 |
| CVE-2022-0563 | 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 containing data from the file. This flaw allows an unprivileged user to read root-owned files, potentially leading to privilege escalation. This flaw affects util-linux versions prior to 2.37.4. | [email protected] | 5.5 | 0.43% | 2022-02-21 | 2026-06-17 |
| CVE-2021-37600 | 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 in all realistic environments. | [email protected] | 5.5 | 0.66% | 2021-07-30 | 2026-06-17 |
| CVE-2020-10751 | A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly only validate the first netlink message in the skb and allow or deny the rest of the messages within the skb with the granted permission without further processing. | [email protected] | 6.1 | 0.35% | 2020-05-26 | 2026-06-17 |
| CVE-2018-17953 | A incorrect variable in a SUSE specific patch for pam_access rule matching in PAM 1.3.0 in openSUSE Leap 15.0 and SUSE Linux Enterprise 15 could lead to pam_access rules not being applied (fail open). | [email protected] | 7.5 | 1.34% | 2018-11-27 | 2026-06-17 |
| CVE-2018-7738 | 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 followed by a tab character for autocompletion. | [email protected] | 7.8 | 0.46% | 2018-03-07 | 2026-06-17 |
| CVE-2015-5224 | The mkostemp function in login-utils in util-linux when used incorrectly allows remote attackers to cause file name collision and possibly other attacks. | [email protected] | 9.8 | 4.53% | 2017-08-23 | 2026-06-17 |
| CVE-2016-5011 | 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. | [email protected] | 4.6 | 0.46% | 2017-04-11 | 2026-06-17 |
| CVE-2014-9114 | Blkid in util-linux before 2.26rc-1 allows local users to execute arbitrary code. | [email protected] | 7.8 | 0.65% | 2017-03-31 | 2026-06-17 |
| CVE-2016-2779 | runuser in util-linux allows local users to escape to the parent session via a crafted TIOCSTI ioctl call, which pushes characters to the terminal's input buffer. | [email protected] | 7.8 | 0.39% | 2017-02-07 | 2026-06-17 |
| CVE-2015-5218 | 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. | [email protected] | 2.1 | 0.61% | 2015-11-09 | 2026-06-17 |
| CVE-2013-0157 | (a) mount and (b) umount in util-linux 2.14.1, 2.17.2, and probably other versions allow local users to determine the existence of restricted directories by (1) using the --guess-fstype command-line option or (2) attempting to mount a non-existent device, which generates different error messages depending on whether the directory exists. | [email protected] | 2.1 | 0.38% | 2014-01-21 | 2026-06-16 |
| CVE-2009-3288 | The sg_build_indirect function in drivers/scsi/sg.c in Linux kernel 2.6.28-rc1 through 2.6.31-rc8 uses an incorrect variable when accessing an array, which allows local users to cause a denial of service (kernel OOPS and NULL pointer dereference), as demonstrated by using xcdroast to duplicate a CD. NOTE: this is only exploitable by users who can open the cdrom device. | [email protected] | 4.9 | 0.44% | 2009-09-22 | 2026-06-16 |
| CVE-2007-6712 | Integer overflow in the hrtimer_forward function (hrtimer.c) in Linux kernel 2.6.21-rc4, when running on 64-bit systems, allows local users to cause a denial of service (infinite loop) via a timer with a large expiry value, which causes the timer to always be expired. | [email protected] | 4.9 | 0.39% | 2008-04-12 | 2026-06-16 |
| CVE-2007-5191 | 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. | [email protected] | 7.2 | 0.44% | 2007-10-04 | 2026-06-16 |
