AI-suggested

An official patch is available and should be applied to affected Linux kernel versions. The fix moves driver registration out of the probe() callback to the module initcall and ensures proper unregistration on module exit. Users should update to patched kernel versions as provided by their Linux distribution vendors, such as the Ubuntu security notice USN-8492-1. No additional mitigation steps are required beyond applying the official update.

Description

A vulnerability in the Linux kernel's GPIO subsystem related to the OMAP platform was resolved. The issue involved improper driver registration within a probe() callback, which could cause a deadlock due to device locking rules. Additionally, the omap_mpuio_driver was not properly unregistered upon module unload. This flaw was fixed by moving driver registration to the module initialization and unregistering it on module exit. Multiple Linux kernel versions are affected, and a patch is available.
