There is a BUG: KMSAN: uninit-value in hci_cmd_complete_evt() due to a
malformed HCI event packet received from userspace.

The existing code in hci_event_packet() checks that the buffer is large
enough to contain the event header, and checks that the hdr's Event Code
is valid, but does not check the hdr's Parameter Total Length. So,
syzbot’s event packet passes through and uses the un-init values in
hci_event_func() => hci_cmd_complete_evt().

Hi,

This is the friendly patch-bot of Greg Kroah-Hartman.  You have sent him
a patch that has triggered this response.  He used to manually respond
to these common problems, but in order to save his sanity (he kept
writing the same thing over and over, yet to different people), I was
created.  Hopefully you will not take offence and will fix the problem
in your patch and resubmit it so that it can be accepted into the Linux
kernel tree.

You are receiving this message because of the following common error(s)
as indicated below:

- You have marked a patch with a "Fixes:" tag for a commit that is in an
  older released kernel, yet you do not have a cc: stable line in the
  signed-off-by area at all, which means that the patch will not be
  applied to any older kernel releases.  To properly fix this, please
  follow the documented rules in the
  Documentation/process/stable-kernel-rules.rst file for how to resolve
  this.

If you wish to discuss this problem further, or you have questions about
how to resolve this issue, please feel free to respond to this email and
Greg will reply once he has dug out from the pending patches received
from other developers.

thanks,

greg k-h's patch email bot

It does checks the length:

    if (skb->len < ev->min_len) {
        bt_dev_err(hdev, "unexpected event 0x%2.2x length: %u < %u",
               event, skb->len, ev->min_len);
        return;
    }

Looks like a big hammer for a uninitialized value, which I assume is
from the following code:

    if (i == ARRAY_SIZE(hci_cc_table)) {
        /* Unknown opcode, assume byte 0 contains the status, so
         * that e.g. __hci_cmd_sync() properly returns errors
         * for vendor specific commands send by HCI drivers.
         * If a vendor doesn't actually follow this convention we may
         * need to introduce a vendor CC table in order to properly set
         * the status.
         */
        *status = skb->data[0];
    }

That one is accessing skb->data without first checking it like
hci_cc_skb_pull like all other event handlers are doing, if that is
really the case then something like the following should make it go
away:

In hci_cmd_complete_evt(), if the command complete event has an unknown
opcode, we assume the first byte of the remaining skb->data contains the
return status. However, parameter data has previously been pulled in
hci_event_func(), which may leave the skb empty. If so, using skb->data[0]
for the return status uses un-init memory.

The fix is to check skb->len before using skb->data.

changes in v2:
- check skb->len before accessing skb->data in hci_cmd_complete_evt(). 
- remove v1’s changes
- update commit message and Fixes tag 

Thank you for the response Luiz. I didn’t want to spam you or the ML
