CVE-2026-72062: gpio: mt7621: avoid corruption of shared interrupt trigger state
In the Linux kernel, the following vulnerability has been resolved:
gpio: mt7621: avoid corruption of shared interrupt trigger state
The bank-shared fields like 'rising' and 'falling' are modified using non-atomic read-modify-write operations. Since every gpio chip instance represents an entire bank of 32 pins, if 'mediatekgpioirqtype()' is called concurrently for different IRQs on the same bank a possible overwrite of each other's configuration is possible. Thus, protect this state with 'gpiogenericlockirqsave' lock in the same way it is handled in irpchip 'mediatekgpioirqmask()' and 'mediatekgpioirqunmask()' callbacks.
