  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ns390/vfio_ccw: Implement a crw lock\n\nUnlike the channel_program struct, which covers synchronous I/O\nsubmissions and asynchronous interrupts, the CRW region relies\nexclusively on asynchronous events coming from hardware.\n\nImplement a lock to manage the list of those payloads, to ensure\nthey are read cohesively.",
