Description

This security bulletin contains information about 1 security vulnerability.


1) Loop with Unreachable Exit Condition ('Infinite Loop') (CVE-ID: CVE-2025-71267)

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

The vulnerability exists due to an infinite loop in the ntfs3 file system driver when processing a malformed NTFS image with a zero-sized ATTR_LIST attribute. A local attacker can mount a specially crafted NTFS image to cause a denial of service.

The attacker needs physical or local access to insert or mount the malicious NTFS image; no authentication beyond mounting the filesystem is required. The system becomes unresponsive during mount due to an infinite loop in kernel space.
