CVE-2026-72062

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
