In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: fix double list_add at iwl_mvm_mac_wake_tx_queue
After successfull station association, if station queues are disabled for some reason, the related lists are not emptied. So if some new element is added to the list in iwl_mvm_mac_wake_tx_queue, it can match with the old one and produce a BUG like this:
[ 46.535263] list_add corruption. prev->next should be next (ffff94c1c318a360), but was 0000000000000000. (prev=ffff94c1d02d3388).

In order to avoid this problem, we must also remove the related lists when station queues are disabled.
