Description OSIDB Bzimport 2026-09-17 19:35:05 UTC 
In the Linux kernel, the following vulnerability has been resolved:

pinctrl: airoha: add missed IRQ resource helpers

Without hooking .irq_request_resources, gpiolib cannot set
GPIOD_FLAG_USED_AS_IRQ. This breaks pin direction locking and can allow
userspace or another driver to reconfigure an active IRQ pin as an output
