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.
