Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
wifi: rt2x00: Fix memory leak when handling surveys
When removing a rt2x00 device, its associated channel surveys are not freed, causing a memory leak observable with kmemleak:

Fix this by freeing the channel surveys on device removal.
Tested with a RT3070 based USB wireless adapter.
