CVE-2026-35374 uutils coreutils split Arbitrary File Truncation via Time-of-Check to Time-of-Use (TOCTOU) Race Condition

A Time-of-Check to Time-of-Use TOCTOU vulnerability exists in the split utility of uutils coreutils. The program attempts to prevent data loss by checking for identity between input and output files using their file paths before initiating the split operation. However, the utility subsequently...

CVE-2026-35374 uutils coreutils split Arbitrary File Truncation via Time-of-Check to Time-of-Use (TOCTOU) Race Condition

CVE-2026-35374

The CVE concerns the split utility of uutils coreutils, where a TOCTOU race exists between a path-based check and subsequent opening with truncation. An attacker with directory write access can swap path components (e.g., via a symlink) during the race, causing split to truncate and write to an u...

CVE-2026-35373 uutils coreutils ln Local Denial of Service via Improper Handling of Non-UTF-8 Filenames

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...

CVE-2026-35373

The CVE-2026-35373 issue affects the ln utility in uutils/coreutils. A logic error causes ln to reject source paths containing non-UTF‑8 filename bytes when using target-directory forms (for example, ln SOURCE... DIRECTORY). Unlike GNU ln, which treats filenames as raw bytes, the uutils implement...

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-2026-35372 uutils coreutils ln Security Bypass via Improper Handling of the --no-dereference Flag

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-2026-35372

Affects the ln utility in uutils coreutils. A logic error causes dereferencing of the target when --no-dereference/-n is provided, previously only honoring no-dereference with --force. This can cause ln to follow a symlink pointing to a directory and create links inside that directory instead of ...

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-2026-35371

CVE-2026-35371 uutils coreutils id Misleading Identity Reporting in Pretty Print Mode

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-2026-35370

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...

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...
