From this webpage screenshot, the following key information about the vulnerability can be obtained: Vulnerability Description: A kernel crash occurs when accessing the IRQ handler associated with a generated IRQ during IRQ (Interrupt Request) processing. This is resolved by acquiring a spinlock and saving the current interrupt state, then using to handle the interrupt request. Fix Measures: - Use instead of to process interrupts. - After determining which GPIO triggered the interrupt and attempting to call , a kernel crash occurs; this issue needs to be fixed.
