GHSA-q5jc-r55m-4xv5 
In the Linux kernel, the following vulnerability has been resolved:fs/ntfs3: Enhance sanity check while generating attr_listni_create_attr_list uses WARN_ON to catch error cases while generating
attribute list, which only prints out stack trace and may not be enough.
This repalces them with more proper error handling flow.[   59.666332] BUG: kernel NULL pointer dereference, address: 000000000000000e
