UBUNTU-CVE-2025-71267: High severity ubuntu/linux-hwe-edge vulnerability

Q: What systems are realistically exposed to this denial of service?

Systems that mount malformed NTFS images using the ntfs3 file system driver are exposed. The affected Ubuntu kernel packages listed are linux, linux-realtime, linux-azure, linux-gcp, linux-azure-fde, linux-riscv, linux-gke, and linux-gkeop.

Q: What must an attacker provide to trigger the issue?

An attacker needs to provide a malformed NTFS image containing a resident ATTR_LIST attribute with a zero data size. Processing that image during mount causes the ntfs3 driver to repeatedly reload the attribute list.

Q: What is the operational impact if exploitation succeeds?

The NTFS mount operation does not complete and a kernel thread hangs in an infinite loop. This results in a denial-of-service condition.

Q: How does the fix prevent the issue?

The fix validates that ATTR_LIST data_size is non-zero before allocating memory. A zero-sized ATTR_LIST is rejected with -EINVAL instead of being processed.

Updated

In the Linux kernel, the following vulnerability has been resolved: fs: ntfs3: fix infinite loop triggered by zero-sized ATTRLIST 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 ATTRLIST attribute indicates a zero data size while the driver allocates memory for it. When ntfsloadattrlist() processes a resident ATTRLIST with datasize set to zero, it still allocates memory because of alaligned(0). This creates an inconsistent state where ni->attrlist.size is zero, but ni->attrlist.le is non-null. This causes nienumattrex to incorrectly assume that no attribute list exists and enumerates only the primary MFT record. When it finds ATTRLIST, 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 datasize is non-zero before memory allocation. When a zero-sized ATTRLIST is detected, the function returns -EINVAL, preventing a DoS vulnerability.

Frequently Asked Questions

What systems are realistically exposed to this denial of service?

Systems that mount malformed NTFS images using the ntfs3 file system driver are exposed. The affected Ubuntu kernel packages listed are linux, linux-realtime, linux-azure, linux-gcp, linux-azure-fde, linux-riscv, linux-gke, and linux-gkeop.

What must an attacker provide to trigger the issue?

An attacker needs to provide a malformed NTFS image containing a resident ATTR_LIST attribute with a zero data size. Processing that image during mount causes the ntfs3 driver to repeatedly reload the attribute list.

What is the operational impact if exploitation succeeds?

The NTFS mount operation does not complete and a kernel thread hangs in an infinite loop. This results in a denial-of-service condition.

How does the fix prevent the issue?

The fix validates that ATTR_LIST data_size is non-zero before allocating memory. A zero-sized ATTR_LIST is rejected with -EINVAL instead of being processed.
