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.","state":0,"publishedAt":"2026-08-26T14:37:18.159+00:00","modifiedAt":"2026-10-16T19:26:25.722+00:00","affected":[{"ecosystem":"Vendor
