This issue affects the function ntfs_load_attr_list of the component ntfs3. Executing a manipulation can lead to denial of service. This vulnerability is registered as CVE-2025-71267. No exploit is available. It is advisable to upgrade the affected component. Detailsinfo A vulnerability was found in Linux Kernel up to 6.19.5. It has been declared as critical. This vulnerability affects the function ntfs_load_attr_list of the component ntfs3. The manipulation with an unknown input leads to a denial of service vulnerability. The CWE definition for the vulnerability is CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. As an impact it is known to affect availability. CVE summarizes: In the Linux kernel, the following vulnerability has been resolved: fs: ntfs3: fix infinite loop triggered by zero-sized ATTR_LIST We found an infinite loop bug in the ntfs3 file system that can lead to a Denial-of-Service (DoS) condition. A malformed NTFS image can cause an infinite loop when an ATTR_LIST attribute indicates a zero data size while the driver allocates memory for it. When ntfs_load_attr_list() processes a resident ATTR_LIST with data_size set to zero, it still allocates memory because of al_aligned(0). This creates an inconsistent state where ni->attr_list.size is zero, but ni->attr_list.le is non-null. This causes ni_enum_attr_ex to incorrectly assume that no attribute list exists and enumerates only the primary MFT record. When it finds ATTR_LIST, the code reloads it and restarts the enumeration, repeating indefinitely. The mount operation never completes, hanging the kernel thread. This patch adds validation to ensure that data_size is non-zero before memory allocation. When a zero-sized ATTR_LIST is detected, the function returns -EINVAL, preventing a DoS vulnerability. The advisory is shared for download at git.kernel.org. This vulnerability was named CVE-2025-71267 since 03/17/2026. There are known technical details, but no exploit is available. Upgrading to version 5.15.202, 6.1.165, 6.6.128, 6.12.75, 6.18.16, 6.19.6 or 7.0-rc1 eliminates this vulnerability.
