CVE-2026-35362 Details
Description
The safe_traversal 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 these protections, leaving directory traversal operations vulnerable to symlink race conditions.
A vulnerability exists in the safe_traversal module of uutils coreutils, which is designed to protect against Time-of-Check to Time-of-Use (TOCTOU) symlink races by using file-descriptor-relative syscalls. However, this protection is mistakenly restricted to Linux. On other Unix-like systems, such as macOS and FreeBSD, the utility does not apply these safeguards, leaving directory traversal operations exposed to symlink race vulnerabilities.
Users can update to uutils coreutils version 0.6.0, which includes the necessary fix to expand safe directory traversal to all Unix platforms.
