Security fixes:
CVE-2026-27456 - mount(8) TOCTOU symlink attack via loop device.
The SUID mount follows symlinks when resolving loop backing file
paths. On systems where non-root users are permitted to mount loop
devices (via 'user' option in fstab), this allows access to
arbitrary files.
CWE-190 - Integer overflow in libblkid parse_dos_extended().
A crafted MBR disk image can cause uint32_t wraparound in EBR
chain processing, causing reported partitions to not match the
on-disk layout. Tools like udisks may then register a partition
at logical sector 0.
