Subject: Potential NULL pointer deference in iwlwifi: mvm
Date: Mon, 7 Oct 2019 12:19:11 -0700 [thread overview]
Message-ID: <CABvMjLRhqCAs-r3LA4nX_5tBj=hQeUfb4g5gHf8ghRdwWqKuPA@mail.gmail.com> (raw)
Hi All:
drivers/net/wireless/intel/iwlwifi/mvm/scan.c:
Inside function iwl_mvm_power_ps_disabled_iterator(),
iwl_mvm_vif_from_mac80211()
could return NULL,however, the return value of
iwl_mvm_vif_from_mac80211() is not checked and get
used. This could potentially be unsafe.
