CVE-2026-53615 util-linux libblkid DOS extended-partition overflow produces invalid partition metadata

util-linux is a random collection of Linux utilities. Before util-linux 2.41.4, parsedosextended 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...

CVE-2026-53615

The util-linux utility suite is vulnerable to an integer overflow (CWE-190) in the libblkid component, specifically within the parse_dos_extended() function in libblkid/src/partitions/dos.c. The flaw occurs because the software uses 32-bit addition to compute an extended-partition start sector wi...

Design/Logic Flaw

The parsedosextended function in partitions/dos.c in the libblkid library in util-linux allows physically proximate attackers to cause a denial of service memory consumption via a crafted MSDOS partition table with an extended partition boot record at zero offset...
