  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nsoc: xilinx: Fix race condition in event registration\n\nThe zynqmp_power driver registers handlers for suspend and subsystem\nrestart events using register_event(). 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.",
