uutils coreutils touch Arbitrary File Truncation via TOCTOU Race Condition_CVE-2026-35360

{
    "lastseen": "",
    "description": "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 O_TRUNC. An attacker can exploit this window to create a file or swap a symlink at the target path, causing touch to truncate an existing file and leading to permanent data loss.",
