CVE-2024-50196 is a vulnerability in the Linux kernel's pinctrl driver for the ocelot platform that can cause a system hang when handling level-based interrupts. The issue arises because the interrupt handling functions chained_irq_enter() and chained_irq_exit() are only called if pending interrupts are detected inside a loop. In certain hardware configurations where a GPIO pin is set to level mode but the parent interrupt controller is in edge mode, the GPIO interrupt may be cleared by hardware before the parent interrupt is serviced, causing the system to hang. The fix moves these function calls outside the loop to ensure they are always executed, preventing the hang.
