Hi,

The following vulnerability was published for rust-coreutils.

CVE-2026-35341[0]:
| A vulnerability in uutils coreutils mkfifo allows for the
| unauthorized modification of permissions on existing files. When
| mkfifo fails to create a FIFO because a file already exists at the
| target path, it fails to terminate the operation for that path and
| continues to execute a follow-up set_permissions call. This results
| in the existing file's permissions being changed to the default mode
| (often 644 after umask), potentially exposing sensitive files such
| as SSH private keys to other users on the system.
