Description

This security bulletin contains information about 1 vulnerability.


1) Integer overflow (CVE-ID: CVE-2026-72200)

CWE-ID: CWE-190 - Integer overflow

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to integer overflow in the NTFS mapping-pairs parser when parsing a corrupted NTFS attribute. A local user can supply a crafted NTFS runlist to cause a denial of service.

The issue can occur when a mapping-pairs entry sets the accumulated LCN to S64_MAX and a subsequent entry adds a delta of 1.
