Potential NULL pointer deference in iwlwifi

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi All:

drivers/net/wireless/intel/iwlwifi/mvm/power.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.
