State: Published
Severity: Not scored

Reserved: Feb 26, 2025

Description

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:
