In the Linux kernel, the following vulnerability has been resolved: soc: xilinx: Fix race condition in event registration The zynqmp_power driver registers handlers for suspend and subsystem restart events using register_event(). However, the work structures (zynqmp_pm_init_suspend_work and zynqmp_pm_init_restart_work) used by these handlers were allocated and initialized after the registration call. This created a race window where, if the firmware triggered an event immediately after registration but before allocation, the callback (suspend_event_callback or subsystem_restart_event_callback) would dereference a NULL pointer in work_pending(), leading to a crash. Fix this by allocating and initializing the work structures before registering the events.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
