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...

CVE-2026-35342

The mktemp utility in uutils coreutils fails to properly handle an empty TMPDIR environment variable. Unlike GNU mktemp, which falls back to /tmp when TMPDIR is an empty string, the uutils implementation treats the empty string as a valid path. This causes temporary files to be created in the...

CVE-2026-35346

The comm utility in uutils coreutils silently corrupts data by performing lossy UTF-8 conversion on all output lines. The implementation uses String::fromutf8lossy, which replaces invalid UTF-8 byte sequences with the Unicode replacement character U+FFFD. This behavior differs from GNU comm, whic...

CVE-2026-35347

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...

CVE-2026-35338

A vulnerability in the chmod utility of uutils coreutils allows users to bypass the --preserve-root safety mechanism. The implementation only validates if the target path is literally / and does not canonicalize the path. An attacker or accidental user can use path variants such as /../ or symbol...

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-2026-35363

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-2026-35373

A logic error in the ln utility of uutils coreutils causes the program to reject source paths containing non-UTF-8 filename bytes when using target-directory forms e.g., ln SOURCE... DIRECTORY. While GNU ln treats filenames as raw bytes and creates the links correctly, the uutils implementation...

UBUNTU-CVE-2026-35347

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...

UBUNTU-CVE-2026-35370

The id utility in uutils coreutils miscalculates the groups= section of its output. The implementation uses a user's real GID instead of their effective GID to compute the group list, leading to potentially divergent output compared to GNU coreutils. Because many scripts and automated processes...

UBUNTU-CVE-2026-35361

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...

CVE-2026-35365

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...

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...

UBUNTU-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...

UBUNTU-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...

CVE-2026-35345

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-2026-35379

A logic error in the tr utility of uutils coreutils causes the program to incorrectly define the :graph: and :print: character classes. The implementation mistakenly includes the ASCII space character 0x20 in the :graph: class and excludes it from the :print: class, effectively reversing the...
