Vulnerability Details CVE-2022-48663
In the Linux kernel, the following vulnerability has been resolved:
gpio: mockup: fix NULL pointer dereference when removing debugfs
We now remove the device's debugfs entries when unbinding the driver.
This now causes a NULL-pointer dereference on module exit because the
platform devices are unregistered *after* the global debugfs directory
has been recursively removed. Fix it by unregistering the devices first.
