Giulio Benetti 40ce6355c9 package/util-linux: security bump to 2.41.5
Security fixes:

 CVE-2026-53613 - mount(8) TOCTOU race on target path.
   The SUID mount does not pin the mount target directory, allowing a
   race between path resolution and the actual mount syscall.  A local
   attacker can swap an ancestor directory component between these
   steps to redirect a mount to an arbitrary location.

 CVE-2026-53612 - mount(8) TOCTOU race on post-mount owner/mode change.
   The X-mount.owner, X-mount.group, and X-mount.mode options use
   path-based lchown()/chmod() after mounting.  An attacker can swap
   the target between mount and the ownership/mode change to gain
   control of arbitrary files.

 CVE-2026-53614 - mount(8) SUID bypass via LIBMOUNT_FORCE_MOUNT2.
   The environment variable LIBMOUNT_FORCE_MOUNT2 is not filtered
   via safe_getenv() in SUID context.  A local attacker can force
   the legacy mount(2) code path, which uses a two-step bind+remount
   or propagation sequence with a window where security flags (nosuid,
   noexec, ...) are not yet applied.
