CVE-2026-89481

CVE-2026-89481 affects the Linux kernel's NVMe over TCP (nvme-tcp) component. The root cause is that nvme_tcp_handle_r2t() does not validate the direction of the request a Ready to Transfer (R2T) refers to. A malicious NVMe controller can send an R2T for a READ command; the host then sends the co...

CVE-2026-89480 nvme-tcp: reject a read that transferred too few bytes

CVE-2026-89480

CVE-2026-89480 affects the NVMe-TCP driver in the Linux kernel. The function nvme_tcp_recv_data() completes a read request once the current C2HData PDU is consumed, but no mechanism compares the total bytes received against the length requested by the command. A malicious or faulty NVMe controlle...

kernel: Revert "net/smc: Introduce TCP ULP support"

A flaw was found in the Linux kernel's TCP User-Level Protocol ULP support for SMC. This vulnerability arises when an active TCP socket is converted into an SMC socket, as the implementation attempts to modify core Virtual File System VFS structures in-place. This action violates fundamental VFS...
