CVE-2026-80547

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> s390/vfio_ccw: Implement a crw lock<br /> <br /> Unlike the channel_program struct, which covers synchronous I/O<br /> submissions and asynchronous interrupts, the CRW region relies<br /> exclusively on asynchronous events coming from hardware.<br /> <br /> Implement a lock to manage the list of those payloads, to ensure<br /> they are read cohesively.
