Description OSIDB Bzimport 2025-02-26 03:19:45 UTC 
In the Linux kernel, the following vulnerability has been resolved:

can: mcba_usb: properly check endpoint type

Syzbot reported warning in usb_submit_urb() which is caused by wrong
endpoint type. We should check that in endpoint is actually present to
prevent this warning.

Found pipes are now saved to struct mcba_priv and code uses them
directly instead of making pipes in place.

Fail log:
