CVE-2026-35372

A logic error in the ln utility of uutils coreutils allows the utility to dereference a symbolic link target even when the --no-dereference or -n flag is explicitly provided. The implementation previously only honored the "no-dereference" intent if the --force overwrite mode was also enabled. Thi...

CVE-2026-35367

The nohup utility in uutils coreutils creates its default output file, nohup.out, without specifying explicit restricted permissions. This causes the file to inherit umask-based permissions, typically resulting in a world-readable file 0644. In multi-user environments, this allows any user on the...

CVE-2026-35357

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...

CVE-2026-35350

The cp utility in uutils coreutils fails to properly handle setuid and setgid bits when ownership preservation fails. When copying with the -p preserve flag, the utility applies the source mode bits even if the chown operation is unsuccessful. This can result in a user-owned copy retaining origin...

CVE-2026-35377

A logic error in the env utility of uutils coreutils causes a failure to correctly parse command-line arguments when utilizing the -S split-string option. In GNU env, backslashes within single quotes are treated literally with the exceptions of \ and '. However, the uutils implementation...

CVE-2026-35340

A flaw in the ChownExecutor used by uutils coreutils chown and chgrp causes the utilities to return an incorrect exit code during recursive operations. The final exit code is determined only by the last file processed. If the last operation succeeds, the command returns 0 even if earlier ownershi...

CVE-2026-35339

The recursive mode -R of the chmod utility in uutils coreutils incorrectly handles exit codes when processing multiple files. The final return value is determined solely by the success or failure of the last file processed. This allows the command to return an exit code of 0 success even if error...

CVE-2026-35371

The id utility in uutils coreutils exhibits incorrect behavior in its "pretty print" output when the real UID and effective UID differ. The implementation incorrectly uses the effective GID instead of the effective UID when performing a name lookup for the effective user. This results in misleadi...

CVE-2026-35369

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...

CVE-2026-35380

A logic error in the cut utility of uutils coreutils causes the program to incorrectly interpret the literal two-byte string '' two single quotes as an empty delimiter. The implementation mistakenly maps this string to the NUL character for both the -d delimiter and --output-delimiter options. Th...

CVE-2026-35378

A logic error in the expr utility of uutils coreutils causes the program to evaluate parenthesized subexpressions during the parsing phase rather than at the execution phase. This implementation flaw prevents the utility from performing proper short-circuiting for logical OR | and AND & operation...

CVE-2026-35353

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 ...

UBUNTU-CVE-2026-35380

A logic error in the cut utility of uutils coreutils causes the program to incorrectly interpret the literal two-byte string '' two single quotes as an empty delimiter. The implementation mistakenly maps this string to the NUL character for both the -d delimiter and --output-delimiter options. Th...

UBUNTU-CVE-2026-35349

A vulnerability in the rm utility of uutils coreutils allows a bypass of the --preserve-root protection. The implementation uses a path-string check rather than comparing device and inode numbers to identify the root directory. An attacker or accidental user can bypass this safeguard by using a...

CVE-2026-35363

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...

CVE-2026-35362

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...

UBUNTU-CVE-2026-35378

A logic error in the expr utility of uutils coreutils causes the program to evaluate parenthesized subexpressions during the parsing phase rather than at the execution phase. This implementation flaw prevents the utility from performing proper short-circuiting for logical OR | and AND & operation...

UBUNTU-CVE-2026-35369

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...

UBUNTU-CVE-2026-35368

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...

CVE-2026-35343

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...
