This also keeps\nmac_work from running over an already suspended HIF, which the previous\nsplit (async cancel under the lock, sync cancel after release) would\nhave allowed.","state":0,"publishedAt":"2026-09-11T19:42:11.588+00:00","modifiedAt":"2026-10-19T08:45:22.189+00:00","affected":[{"ecosystem":"Vendor
