  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\ngpio: mt7621: avoid corruption of shared interrupt trigger state\n\nThe bank-shared fields like 'rising' and 'falling' are modified using\nnon-atomic read-modify-write operations. 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.",
