Hi,

The following vulnerability was published for busybox.

CVE-2026-88838[0]:
| A flaw was found in BusyBox's mount utility. A non-root user can
| bypass mount security restrictions set in /etc/fstab by specifying
| clearing-mask options on the command line. These options pass the
| non-root flag filter and are merged with fstab options as strings;
| when the combined options are re-parsed, clearing options can
| override nosuid, nodev, and noexec protections the administrator
| intended to enforce.
