CVE-2026-80655

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.
