In the Linux kernel, the followingvulnerability has been resolved:netlink: Fixwraparounds of sk->sk_rmem_alloc.Netlink has this pattern in some places if (atomic_read(&sk->sk_rmem_alloc)> sk->sk_rcvbuf) atomic_add(skb->truesize, &sk->sk_rmem_alloc);,which hasthe same problem fixed by commit 5a465a0da13e (udp:Fix multiplewraparounds ofsk->sk_rmem_alloc. ).For example,if we set INT_MAX to SO_RCVBUFFORCE, the conditionis always false as the two operands areof int.Then, asingle socket can eat as many skb as possible until OOMhappens, and we can see multiple wraparounds of sk->sk_rmem_alloc.Let s fix it by using atomic_add_return() and comparing the twovariables as unsigned int.Before: [root@fedora ~]# ss -f netlink Recv-Q Send-Q Local Address:Port Peer Address:Port -1668710080 0 rtnl:nl_wraparound/293 *After: [root@fedora ~]# ss -f netlink Recv-Q Send-Q Local Address:Port Peer Address:Port 2147483072 0 rtnl:nl_wraparound/290 * ^ `--- INT_MAX - 576
