## Overview

In the Linux kernel, the following vulnerability has been resolved:

usb: core: hcd: fix possible deadlock in rh control transfers

>From within the SCSI error handler memory allocations must not
trigger IO. Handling errors in UAS and the storage driver may
involve resetting a device. The thread doing the reset itself
relies on VM magic. However, that is insufficient, as resetting
a device involves resuming it. Resumption as well as resetting
involves conrol transfers to the parent of the device to be reset.
That may be a root hub. Hence usbcore must heed the flags passed
to usb_submit_urb() processing control transfers to root hubs.

The problem exist since the storage driver has been merged.

## Remediation

Refer to the linked advisories for vendor-supplied fixes and affected version ranges.
