In the Linux kernel, the following vulnerability has been resolved:
counter: interrupt-cnt: Drop IRQF_NO_THREAD flag
An IRQ handler can either be IRQF_NO_THREAD or acquire spinlock_t, as
CONFIG_PROVE_RAW_LOCK_NESTING warns:
=============================
[ BUG: Invalid wait context ]
6.18.0-rc1+git... #1
-----------------------------
some-user-space-process/1251 is trying to lock:
(&counter->events_list_lock){....}-{3:3}, at: counter_push_event [counter]
other info that might help us debug this:
context-{2:2}
no locks held by some-user-space-process/....
stack backtrace:
CPU: 0 UID: 0 PID: 1251 Comm: some-user-space-process 6.18.0-rc1+git... #1 PREEMPT
Call trace:

call_on_irq_stack

__el0_irq_handler_common
el0t_64_irq_handler
el0t_64_irq
... and Sebastian correctly points out. Remove IRQF_NO_THREAD as an
alternative to switching to raw_spinlock_t, because the latter would limit
all potential nested locks to raw_spinlock_t only.
