UBUNTU-CVE-2026-90258: Medium severity ubuntu/linux-hwe-edge vulnerability
In the Linux kernel, the following vulnerability has been resolved: pinctrl: airoha: add missed IRQ resource helpers Without hooking .irqrequestresources, gpiolib cannot set GPIODFLAGUSEDASIRQ. This breaks pin direction locking and can allow userspace or another driver to reconfigure an active IRQ pin as an output

Event History
Frequently Asked Questions
Which deployments are relevant to this issue?
The affected software list includes ubuntu/linux-riscv, ubuntu/linux-realtime, ubuntu/linux-hwe-edge, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-azure-fde, ubuntu/linux-gke, and ubuntu/linux-aws-5.0. The issue is relevant when the Airoha pinctrl driver manages a pin that is being used as an IRQ.
What conditions are needed for the pin to be reconfigured incorrectly?
An IRQ pin must be active, and userspace or another driver must be able to reconfigure that pin as an output. The missing IRQ resource handling prevents gpiolib from marking the pin as used for an IRQ, so direction locking is not enforced.
