Hi,

The following vulnerability was published for rust-coreutils.

CVE-2026-35360[0]:
| 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.
