In the Linux kernel, the following vulnerability has been resolved:
mptcp: Fix crash due to tcp_tsorted_anchor was initialized before release skb
Got crash when doing pressure test of mptcp:
In __mptcp_alloc_tx_skb skb was allocated and skb->tcp_tsorted_anchor will be initialized, in under memory pressure situation sk_wmem_schedule will return false and then kfree_skb. In this case skb->_skb_refdst is not null because_skb_refdst and tcp_tsorted_anchor are stored in the same mem, and kfree_skb will try to release dst and cause crash.
