Ubuntu.comUB:CVE-2022-48663CVE-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.
