Description OSIDB Bzimport 2025-02-12 14:23:32 UTC 
When changing an alarm, the values of the change mask are evaluated one
after the other, changing the trigger values as requested and eventually,
SyncInitTrigger() is called.
If one of the changes triggers an error, the function will return early,
not adding the new sync object.
This can be used to cause a use after free when the alarm eventually
triggers.
