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...

SECURITY UPDATE: Extended partition loop in MBR partition table leads to DoS - debian/patches/CVE-2016-5011-1.patch: ignore MBR extended partition at zero offset - debian/patches/CVE-2016-5011-2.patch: avoid non-empty recursion in EBR - CVE-2016-5011...

DEBIAN-CVE-2016-5011

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...

util-linux: Extended partition loop in MBR partition table leads to DOS

It was found that util-linux's libblkid library did not properly handle Extended Boot Record EBR partitions when reading MS-DOS partition tables. An attacker with physical USB access to a protected machine could insert a storage device with a specially crafted partition table that could, for...

Updated util-linux packages fix security vulnerability

The util-linux libblkid is vulnerable to a Denial of Service attack during MSDOS partition table parsing, in the extended partition boot record EBR. If the next EBR starts at relative offset 0, parsedosextended will loop until running out of memory. An attacker could install a specially crafted...
