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