CVE-2024-41079Network attack vector

Kernel memory disclosure via uninitialized RDMA result

Published Jul 29, 2024 · Updated Aug 5, 2026

Information disclosure in the NVMe target in Linux allows remote attackers to read kernel memory through NVMe-oF RDMA command replies. The nvmet request initialization path leaves the eight-byte cqe.result field unset, and RDMA completion handling returns its stale contents. An NVMe-oF RDMA target must be configured and network-reachable; pre-authentication command capsules suffice, and the reported consequence is disclosure without modification or service interruption.
