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