Title
wifi: iwlwifi: pcie: fix possible NULL pointer dereference
Summary
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. iwlwifi 0000:01:00.0: Detected crf-id 0xa5a5a5a2, cnv-id 0xa5a5a5a2 wfpm id 0xa5a5a5a2 iwlwifi 0000:01:00.0: Can't find a correct rfid for crf id 0x5a2 ... BUG: kernel NULL pointer dereference, address: 0000000000000028 ...
