AI-suggested
A patch is available that fixes this vulnerability by adding validation to prevent memory allocation for zero-sized ATTR_LIST attributes. Users should apply the official Linux kernel updates containing the fix identified by the provided commit hashes to resolve the issue.
Description
A vulnerability in the Linux kernel's ntfs3 file system driver causes an infinite loop when processing a zero-sized ATTR_LIST attribute. This leads to a Denial-of-Service (DoS) condition by hanging the kernel thread during mount operations. The issue is fixed by adding validation to prevent memory allocation for zero-sized ATTR_LIST attributes.
