Hello, I have tried another script for the semantic patch language out. This source code analysis approach points out that the implementation of the function “prism2sta_inf_hostscanresults” contains still an unchecked call of the function “kmemdup”. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/staging/wlan-ng/prism2sta.c?id=26a7ae2949a86e1b74e2485d725efb528e2a81bb#n1086 https://elixir.bootlin.com/linux/v5.4-rc2/source/drivers/staging/wlan-ng/prism2sta.c#L1086 How do you think about to improve it? Regards, Markus
