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.
