  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nclockevents: Add missing resets of the next_event_forced flag\n\nThe prevention mechanism against timer interrupt starvation missed to reset\nthe next_event_forced flag in a couple of places:\n\n    - When the clock event state changes. That can cause the flag to be\n      stale over a shutdown/startup sequence\n\n    - When a non-forced event is armed, which then prevents rearming before\n      that event. If that event is far out in the future this will cause\n      missed timer interrupts.\n\n    - In the suspend wakeup handler.\n\nThat led to stalls which have been reported by several people.\n\nAdd the missing resets, which fixes the problems for the reporters.",
