Summary
ksmbd: fix slab-out-of-bounds in smb_strndup_from_utf16()
Details

In the Linux kernel, the following vulnerability has been resolved:

ksmbd: fix slab-out-of-bounds in smbstrndupfrom_utf16()

If ->NameOffset of smb2createreq is smaller than Buffer offset of smb2createreq, slab-out-of-bounds read can happen from smb2open. This patch set the minimum value of the name offset to the buffer offset to validate name length of smb2create_req().
