Description
In the Linux kernel, the following vulnerability has been resolved:
irqchip/gic-v3-its: Don't enable interrupts in its_irq_set_vcpu_affinity()
The following call-chain leads to enabling interrupts in a nested interrupt
disabled section:
irq_set_vcpu_affinity()
irq_get_desc_lock()
raw_spin_lock_irqsave() <--- Disable interrupts
its_irq_set_vcpu_affinity()
guard(raw_spinlock_irq) <--- Enables interrupts when leaving the guard()
irq_put_desc_unlock() <--- Warns because interrupts are enabled
This was broken in commit b97e8a2f7130, which replaced the original
raw_spin_[un]lock() pair with guard(raw_spinlock_irq).
Fix the issue by using guard(raw_spinlock).
