  "details": "In the Linux kernel, the following vulnerability has been resolved:  wifi: mac80211: reset the AP_VLAN tailroom counter on ifdown  On ifup, AP_VLAN interfaces get crypto_tx_tailroom_needed_cnt from the AP interface, but it's never decremented again unless the AP is also brought down. Thus, bringing the same AP_VLAN up again will increment the counter again and eventually hit the sanity check:    WARN_ON_ONCE(sdata-\u003ecrypto_tx_tailroom_needed_cnt !=                master-\u003ecrypto_tx_tailroom_needed_cnt);  Reset it on ifdown to avoid that.",
