Summary
In the Linux kernel, the following vulnerability has been resolved:
rtc: spear: initialize IRQ state before requesting alarm IRQ
devm_request_irq() enables the interrupt before it returns, so the handler may run while probe is still initializing the device. Initialize the MMIO address and spinlock before requesting the alarm IRQ.
