Astra Linux – Vulnerability in util-linux

util-linux is a random collection of Linux utilities. Prior to version 2.41.4, a TOCTOU Time-of-Check-Time-of-Use vulnerability was 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...

Astra Linux – Vulnerability in util-linux

The wall function in util-linux up to version 2.40 is often installed with setgid and tty permissions. This allows escape sequences to be sent to other users’ terminals via argv. Specifically, escape sequences received from stdin are blocked, but escape sequences received from argv are not blocke...

ALPINE-CVE-2026-76642

util-linux versions through 2.41.5 and 2.42.2 fail to check mount helper exit status before running post-mount hooks, allowing unprivileged users to execute privileged operations on pre-existing filesystems. Attackers can exploit X-mount.idmap or X-mount.owner hooks to clone filesystems with...

AZL-99081 CVE-2026-76642 affecting package util-linux 2.40.2-5

util-linux versions through 2.41.5 and 2.42.2 fail to check mount helper exit status before running post-mount hooks, allowing unprivileged users to execute privileged operations on pre-existing filesystems. Attackers can exploit X-mount.idmap or X-mount.owner hooks to clone filesystems with...

util-linux: util-linux: nsenter --join-cgroup leaks root cgroup migration authority

The nsenter --join-cgroup option opens the target cgroup.procs file as root and leaves that file descriptor open across later namespace and credential changes and across execve. Because the kernel checks later cgroup migrations using the credentials from the original open, a program run in an...

util-linux: util-linux: restricted bind mounts do not pin the source, allowing X-mount.owner/group/mode redirection

A flaw was found in util-linux. Restricted bind mounts take the source path from fstab but do not pin that source before the privileged mount. A local unprivileged user who can replace the authorized source or a writable ancestor can redirect SUID mount8 to bind another host directory. If the fst...

util-linux: util-linux: failed external mount helper still runs privileged X-mount post-hooks

When an external mount. helper runs but exits with a nonzero status, libmount still treats the helper invocation as successful and runs privileged post-mount hooks. A local unprivileged user with an /etc/fstab entry that uses the user option together with X-mount.idmap or X-mount.owner/group/mode...

util-linux: util-linux: X-mount.subdir detached-tree resolution can escape via intermediate symlinks

The X-mount.subdir option uses a detached-tree fast path on Linux 6.15 and later and passes the configured subdirectory to opentree with ATSYMLINKNOFOLLOW. That flag does not stop intermediate symlink traversal or keep resolution inside the newly mounted filesystem. A local unprivileged user with...
