However, the work structures\n(zynqmp_pm_init_suspend_work and zynqmp_pm_init_restart_work) used by\nthese handlers were allocated and initialized after the registration\ncall.\n\nThis created a race window where, if the firmware triggered an event\nimmediately after registration but before allocation, the callback\n(suspend_event_callback or subsystem_restart_event_callback) would\ndereference a NULL pointer in work_pending(), leading to a crash.\n\nFix this by allocating and initializing the work structures before\nregistering the events.","state":0,"publishedAt":"2026-08-28T06:49:01.988+00:00","modifiedAt":"2026-10-21T12:46:48.145+00:00","affected":[{"ecosystem":"Vendor
