In the Linux kernel, the following vulnerability has been resolved:

ARM: 9317/1: kexec: Make smp stop calls asynchronous

If a panic is triggered by a hrtimer interrupt all online cpus will be
notified and set offline. But as highlighted by commit 19dbdcb8039c
("smp: Warn on function calls from softirq context") this call should
not be made synchronous with disabled interrupts:

softdog: Initiating panic
Kernel panic - not syncing: Software Watchdog Timer expired
WARNING: CPU: 1 PID: 0 at kernel/smp.c:753 smp_call_function_many_cond
unwind_backtrace:
show_stack
dump_stack_lvl

smp_call_function

Make the smp call for machine_crash_nonpanic_core() asynchronous.
