Technical description
In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Fix NULL dereference in ni_write_inode
Syzbot reports a NULL dereference in ni_write_inode.
When creating a new inode, if allocation fails in mi_init function
(called in mi_format_new function), mi->mrec is set to NULL.
In the error path of this inode creation, mi->mrec is later
dereferenced in ni_write_inode.
Add a NULL check to prevent NULL dereference.
