CVE-2026-80789

In the Linux kernel nvmet-tcp component (NVMe/TCP target), a host-controlled 32-bit sgl->length field is only validated for in-capsule SGL descriptors. Non-inline transport SGL data-block descriptors—those used for out-of-capsule writes—skip the check entirely, causing an unbounded sgl_alloc()...

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...

kernel: nvmet-auth: reject short AUTH_RECEIVE buffers

A flaw was found in the nvmet-auth component of the Linux kernel. A remote attacker, by sending a specially crafted AUTHRECEIVE buffer to an NVMe-oF NVM Express over Fabrics target with in-band authentication enabled, can trigger a heap out-of-bounds write. This vulnerability arises because the...
