What it is

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

s390/vfio_ccw: Implement a crw lock

Unlike the channel_program struct, which covers synchronous I/O

submissions and asynchronous interrupts, the CRW region relies

exclusively on asynchronous events coming from hardware.

Implement a lock to manage the list of those payloads, to ensure

they are read cohesively.
