In the Linux kernel, the following vulnerability has been resolved:

net: annotate data-races around sk->sk_{data_ready,write_space}

skmsg (and probably other layers) are changing these pointers

while other cpus might read them concurrently.

Add corresponding READ_ONCE()/WRITE_ONCE() annotations

for UDP, TCP and AF_UNIX.
