CVE-2026-31669

The CVE-2026-31669 entry pertains to the Linux kernel MPTCP code. A use-after-free could occur in IPv6 subflow sockets due to premature copying of tcpv6_prot into tcpv6_prot_override during early init, before proto_register(&tcpv6_prot) and its SLAB_TYPESAFE_BY_RCU cache is established. Consequen...
