Subject: Linux kernel: multiple vulnerabilities in the USB subsystem

Hi!

Below are the details for 14 vulnerabilities found with syzkaller in
the Linux kernel USB subsystem. All of them can be triggered with a
crafted malicious USB device in case an attacker has physical access
to the machine.

There's quite a lot more similar bugs reported [1] but not yet fixed.
