CVE-2021-47591
CVE-2021-47591 affects the Linux kernel. The vulnerability arises from the TCP_ULP setsockopt mechanism, which is no longer supported for MPTCP as it is already used internally to connect subflow sockets to the MPTCP layer. In syzbot testing, a crash (KASAN null dereference) was observed on mptcp...
