- Summary
- wifi: rtw88: use ieee80211_purge_tx_queue() to purge TX skb
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw88: use ieee80211purgetx_queue() to purge TX skb
When removing kernel modules by: rmmod rtw888723cs rtw888703b rtw888723x rtw88sdio rtw88_core
Driver uses skbqueuepurge() to purge TX skb, but not report tx status causing "Have pending ack frames!" warning. Use ieee80211purgetx_queue() to correct this.
Since ieee80211purgetx_queue() doesn't take locks, to prevent racing between TX work and purge TX queue, flush and destroy TX work in advance.
