CVE-2026-72062

Description

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 -mediatek_gpio_irq_type()- 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 -gpio_generic_lock_irqsave- lock in the same way it is handled in irp_chip -mediatek_gpio_irq_mask()- and -mediatek_gpio_irq_unmask()- callbacks.
