CVE-2026-35353: Time-of-check Time-of-use (TOCTOU) Race Condition

The mkdir utility in uutils coreutils incorrectly applies permissions when using the -m flag by creating a directory with umask-derived permissions typically 0755 before subsequently changing them to the requested mode via a separate chmod system call. In multi-user environments, this introduces ...

CVE-2026-35355: Time-of-check Time-of-use (TOCTOU) Race Condition

The install utility in uutils coreutils is vulnerable to a Time-of-Check to Time-of-Use TOCTOU race condition during file installation. The implementation unlinks an existing destination file and then recreates it using a path-based operation without the OEXCL flag. A local attacker can exploit t...

CVE-2026-35362: Time-of-check Time-of-use (TOCTOU) Race Condition

The safetraversal module in uutils coreutils, which provides protection against Time-of-Check to Time-of-Use TOCTOU symlink races using file-descriptor-relative syscalls, is incorrectly limited to Linux targets. On other Unix-like systems such as macOS and FreeBSD, the utility fails to utilize...

Linux Distros Unpatched Vulnerability : CVE-2026-35359

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - A Time-of-Check to Time-of-Use TOCTOU vulnerability in the cp utility of uutils coreutils allows an attacker to bypass no-dereference intent. The utility checks...

CVE-2026-35354: Time-of-check Time-of-use (TOCTOU) Race Condition

A Time-of-Check to Time-of-Use TOCTOU vulnerability exists in the mv utility of uutils coreutils during cross-device moves. The extended attribute xattr preservation logic uses multiple path-based system calls that perform fresh path-to-inode lookups for each operation. A local attacker with writ...

CVE-2026-35359: Time-of-check Time-of-use (TOCTOU) Race Condition

A Time-of-Check to Time-of-Use TOCTOU vulnerability in the cp utility of uutils coreutils allows an attacker to bypass no-dereference intent. The utility checks if a source path is a symbolic link using path-based metadata but subsequently opens it without the ONOFOLLOW flag. An attacker with...

CVE-2026-35345: Time-of-check Time-of-use (TOCTOU) Race Condition

A vulnerability in the tail utility of uutils coreutils allows for the exfiltration of sensitive file contents when using the --follow=name option. Unlike GNU tail, the uutils implementation continues to monitor a path after it has been replaced by a symbolic link, subsequently outputting the...

CVE-2026-35376: Time-of-check Time-of-use (TOCTOU) Race Condition

A Time-of-Check to Time-of-Use TOCTOU vulnerability exists in the chcon utility of uutils coreutils during recursive operations.
