The comm utility in uutils coreutils incorrectly consumes data from non-regular file inputs before performing comparison operations. The arefilesidentical function opens and reads from both input paths to compare content without first verifying if the paths refer to regular files. If an input pat...

EUVD-2026-24973

The cut utility in uutils coreutils incorrectly handles the -s only-delimited option when a newline character is specified as the delimiter. The implementation fails to verify the onlydelimited flag in the cutfieldsnewlinechardelim function, causing the utility to print non-delimited lines that...

EUVD-2026-25012

The mv utility in uutils coreutils improperly handles directory trees containing symbolic links during moves across filesystem boundaries. Instead of preserving symlinks, the implementation expands them, copying the linked targets as real files or directories at the destination. This can lead to...

GHSA-X4MC-MQM7-GG39 uutils coreutils has a Time-of-Check to 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...

GHSA-WH8P-H9HW-X2MC uutils coreutils has an Unchecked Return Value Issue

The dd utility in uutils coreutils suppresses errors during file truncation operations by unconditionally calling Result::ok on truncation attempts. While intended to mimic GNU behavior for special files like /dev/null, the uutils implementation also hides failures on regular files and directorie...

GHSA-MH5C-XRMH-M794 uutils coreutils has an Untrusted Search Path

A vulnerability exists in the chroot utility of uutils coreutils when using the --userspec option. The utility resolves the user specification via getpwnam after entering the chroot but before dropping root privileges. On glibc-based systems, this can trigger the Name Service Switch NSS to load...

GHSA-GPCG-H6X2-C26P uutils coreutils has an Improper Input Validation issue

An argument parsing error in the kill utility of uutils coreutils incorrectly interprets kill -1 as a request to send the default signal SIGTERM to PID -1. Sending a signal to PID -1 causes the kernel to terminate all processes visible to the caller, potentially leading to a system crash or massi...

GHSA-RX8H-33GR-VHJ9 uutils coreutils' comm utility incorrectly consumes data from non-regular file inputs before performing comparison operations

The comm utility in uutils coreutils incorrectly consumes data from non-regular file inputs before performing comparison operations. The arefilesidentical function opens and reads from both input paths to compare content without first verifying if the paths refer to regular files. If an input pat...

GHSA-V24V-F45G-W7JF uutils coreutils has a Time-of-Check to 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...

GHSA-2M8X-MVFX-GWGJ uutils coreutils has a Time-of-check Time-of-use (TOCTOU) Race Condition

The cp utility in uutils coreutils is vulnerable to an information disclosure race condition. Destination files are initially created with umask-derived permissions e.g., 0644 before being restricted to their final mode e.g., 0600 later in the process. A local attacker can race to open the file...

GHSA-79RC-QPW3-JV92 uutils coreutils has an Improper Preservation of Permissions issue

The mknod utility in uutils coreutils fails to handle security labels atomically by creating device nodes before setting the SELinux context. If labeling fails, the utility attempts cleanup using std::fs::removedir, which cannot remove device nodes or FIFOs. This leaves mislabeled nodes behind wi...

uutils coreutils has an Improper Input Validation issue

An argument parsing error in the kill utility of uutils coreutils incorrectly interprets kill -1 as a request to send the default signal SIGTERM to PID -1. Sending a signal to PID -1 causes the kernel to terminate all processes visible to the caller, potentially leading to a system crash or massi...

uutils coreutils has a Time-of-check Time-of-use (TOCTOU) Race Condition

A Time-of-Check to Time-of-Use TOCTOU race condition exists in the mv utility of uutils coreutils during cross-device operations. The utility removes the destination path before recreating it through a copy operation. A local attacker with write access to the destination directory can exploit thi...

uutils coreutils has a Time-of-Check to Time-of-Use (TOCTOU) race condition

A Time-of-Check to Time-of-Use TOCTOU vulnerability exists in the install utility of uutils coreutils when using the -D flag. The command creates parent directories and subsequently performs a second path resolution to create the target file, neither of which is anchored to a directory file...

uutils coreutils has a Path Traversal issue

A vulnerability in the rm utility of uutils coreutils allows the bypass of safeguard mechanisms intended to protect the current directory. While the utility correctly refuses to delete . or .., it fails to recognize equivalent paths with trailing slashes, such as ./ or .///. An accidental or...

uutils coreutils has an Issue With its Always-Incorrect Control Flow Implementation

The cut utility in uutils coreutils incorrectly handles the -s only-delimited option when a newline character is specified as the delimiter. The implementation fails to verify the onlydelimited flag in the cutfieldsnewlinechardelim function, causing the utility to print non-delimited lines that...

uutils coreutils has a Time-of-check Time-of-use (TOCTOU) Race Condition

GHSA-957R-R8GC-VV3H uutils coreutils doesn't preserve file ownership during moves across different filesystem boundaries

The mv utility in uutils coreutils fails to preserve file ownership during moves across different filesystem boundaries. The utility falls back to a copy-and-delete routine that creates the destination file using the caller's UID/GID rather than the source's metadata. This flaw breaks backups and...

GHSA-Q6M9-XJ2W-XMRC uutils coreutils has a Time-of-check Time-of-use (TOCTOU) Race Condition

The touch utility in uutils coreutils is vulnerable to a Time-of-Check to Time-of-Use TOCTOU race condition during file creation. When the utility identifies a missing path, it later attempts creation using File::create, which internally uses OTRUNC. An attacker can exploit this window to create ...
