CVE-2026-80788

CVE-2026-80788 affects the Linux kernel NVMe-over-TCP target subsystem (nvmet-tcp ). A remote NVMe initiator can send a command with an oversized SGL (Scatter Gather List) field, causing nvmet_tcp_map_data() to allocate over one million scatterlist/iovec entries. This exceeds MAX_PAGE_ORDER , tri...
