CVE-2026-31425

A flaw was found in the Linux kernel. A local user can trigger a null pointer dereference in the Reliable Datagram Sockets RDS over InfiniBand IB component. This occurs when sendmsg with RDSCMSGRDMAMAP is called on a new outgoing connection before the IB connection is fully established. Successfu...
