In the Linux kernel, the following vulnerability has been resolved:
ksmbd: validate session id and tree id in compound request
smb2_get_msg() in smb2getksmbdtcon() and smb2checkusersession()
will always return the first request smb2 header in a compound request.
if SMB2_TREE_CONNECT_HE is the first command in compound request, will
return 0, i.e. The tree id check is skipped.
This patch use ksmbdreqbuf_next() to get current command in compound.
