Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: use ieee80211_purge_tx_queue() to purge TX skb
When removing kernel modules by: rmmod rtw88_8723cs rtw88_8703b rtw88_8723x rtw88_sdio rtw88_core
Driver uses skb_queue_purge() to purge TX skb, but not report tx status causing "Have pending ack frames!" warning. Use ieee80211_purge_tx_queue() to correct this.
Since ieee80211_purge_tx_queue() doesn't take locks, to prevent racing between TX work and purge TX queue, flush and destroy TX work in advance.
