In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: pcie: fix possible NULL pointer dereference
It is possible that iwl_pci_probe() will fail and free the trans, then afterwards iwl_pci_remove() will be called and crash by trying to access trans which is already freed, fix it.
