CVE-2026-56135 is a heap buffer overflow vulnerability in ntfs-3g affecting the build_inherited_id() function during construction of inherited ACL data. The flaw is triggered when ntfs-3g processes a specially crafted or corrupted NTFS filesystem image containing manipulated ACL metadata and related attributes. Improper bounds handling during inherited ACL processing can cause a write beyond the bounds of a heap-allocated buffer, resulting in memory corruption. Because ntfs-3g is commonly used to parse and mount NTFS filesystems through FUSE and may handle attacker-controlled filesystem content, successful exploitation can occur during processing of malicious NTFS structures.
