"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: reset the AP_VLAN tailroom counter on ifdown\n\nOn ifup, AP_VLAN interfaces get crypto_tx_tailroom_needed_cnt from\nthe AP interface, but it's never decremented again unless the AP is\nalso brought down. Thus, bringing the same AP_VLAN up again will\nincrement the counter again and eventually hit the sanity check:\n\n WARN_ON_ONCE(sdata->crypto_tx_tailroom_needed_cnt !=\n master->crypto_tx_tailroom_needed_cnt);\n\nReset it on ifdown to avoid that."
