- Summary
- bpf, sockmap: Fix more uncharged while msg has more_data
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
bpf, sockmap: Fix more uncharged while msg has more_data
In tcpbpfsendverdict(), if msg has more data after tcpbpfsendmsgredir():
tcpbpfsendverdict() tosend = msg->sg.size //msg->sg.size = 22220 case _SKREDIRECT: skmsgreturn() //uncharged msg->sg.size(22220) sk->skforwardalloc tcpbpfsendmsgredir() //after tcpbpfsendmsgredir, msg->sg.size=11000 goto moredata; tosend = msg->sg.size //msg->sg.size = 11000 case _SKREDIRECT: skmsgreturn() //uncharged msg->sg.size(11000) to sk->skforwardalloc
The msg->sg.size(11000) has been uncharged twice, to fix we can charge the remaining msg->sg.size before goto more data.
