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