CVE-2026-35360
MEDIUM6.3EPSS 0.01%uutils coreutils has a Time-of-check Time-of-use (TOCTOU) Race Condition
Published: 4/22/2026Modified: 6/1/2026
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.
