Since every gpio chip instance\nrepresents an entire bank of 32 pins, if 'mediatek_gpio_irq_type()' is\ncalled concurrently for different IRQs on the same bank a possible overwrite\nof each other's configuration is possible. Thus, protect this state with\n'gpio_generic_lock_irqsave' lock in the same way it is handled in irp_chip\n'mediatek_gpio_irq_mask()' and 'mediatek_gpio_irq_unmask()' callbacks.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
