CVE-2026-46572

Description

A flaw was found in ntfs-3g. This vulnerability allows a local attacker to achieve privilege escalation or cause a denial of service (DoS) by corrupting system memory. By providing a specially crafted NTFS filesystem image and creating a file within a malicious directory, an attacker can trigger a heap-based buffer overflow in the directory indexing component. When ntfs-3g runs with elevated permissions (SUID-root), this memory corruption can be leveraged to execute arbitrary code with root privileges.

Statement
