Recent Kernel Util Linux Security Vulnerabilities
wall in util-linux through 2.40, often installed with setgid tty permissions
CVE-2024-28085
- March 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. (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.
An issue was discovered in hwclock.13-v2.27
CVE-2020-21583
6.7 - Medium
- August 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.
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
CVE-2021-3996
5.5 - Medium
- August 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 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.

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
CVE-2021-3995
5.5 - Medium
- August 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 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.
Files or Directories Accessible to External Parties
A flaw was found in the util-linux chfn and chsh utilities when compiled with Readline support
CVE-2022-0563
5.5 - Medium
- February 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 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.
Generation of Error Message Containing Sensitive Information
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
CVE-2021-37600
5.5 - Medium
- July 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 in all realistic environments.
Integer Overflow or Wraparound
In util-linux before 2.32-rc1, bash-completion/umount
CVE-2018-7738
7.8 - High
- March 07, 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 followed by a tab character for autocompletion.
The mkostemp function in login-utils in util-linux when used incorrectly
CVE-2015-5224
9.8 - Critical
- August 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.
The parse_dos_extended function in partitions/dos.c in the libblkid library in util-linux
CVE-2016-5011
4.6 - Medium
- April 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.
Blkid in util-linux before 2.26rc-1
CVE-2014-9114
7.8 - High
- March 31, 2017
Blkid in util-linux before 2.26rc-1 allows local users to execute arbitrary code.
Command Injection
script command in the util-linux package before 2.11n
CVE-2001-1494
5.5 - Medium
- December 31, 2001
script command in the util-linux package before 2.11n allows local users to overwrite arbitrary files by setting a hardlink from the typescript log file to any file on the system, then having root execute the script command.
