Summary
util-linux security update
Details

The util-linux package contains a random collection of files that implements some low-level basic linux utilities.

Security Fix(es):

util-linux is a random collection of Linux utilities. Before util-linux 2.41.4, parse_dos_extended() in libblkid/src/partitions/dos.c computes an extended-partition start sector with 32-bit addition and does not apply the extended-area bounds checks to the first two EBR entries. A local attacker who causes a crafted DOS extended-partition disk image or removable medium to be probed can wrap cur_start + start to sector zero and cause libblkid to report a false partition overlapping the MBR. This directly compromises the integrity of the reported partition metadata; disk modification or availability loss requires a separate downstream consumer to act on that metadata. This issue is fixed in 2.41.4.(CVE-2026-53615)
