CVE-2026-90414

CVE-2026-90414 affects the Linux kernel's ib_isert (InfiniBand iSCSI Target) module. The root cause is that isert_recv_done() passes received PDUs to opcode handlers without validating the HCA-reported wc->byte_len against the initiator-declared data-segment length (dlength). Handlers such as ...

CVE-2026-90414 IB/isert: reject PDUs declaring more data than was received

In the Linux kernel, the following vulnerability has been resolved: IB/isert: reject PDUs declaring more data than was received isertrecvdone hands each received PDU to the opcode handlers without ever looking at wc-bytelen, the number of bytes the HCA actually placed in the receive descriptor. T...

CVE-2026-90413

CVE-2026-90413 is a slab-out-of-bounds read in the Linux kernel's iSCSI target over RDMA (isert) subsystem. The root cause is that isert_rx_login_req() copies only the actually-received bytes into a fixed 8192-byte buffer, but subsequent login handlers (iscsi_target_locate_portal() and iscsi_deco...

CVE-2026-90294

CVE-2026-90294 is a NULL pointer dereference in the Linux kernel's iSCSI over RDMA target (iSER) module. The root cause is a race condition: isert_put_login_tx() transmits the final Login Response before __transport_register_session() completes, so an initiator that immediately issues a SCSI comm...

kernel: IB/isert: Reject login PDUs shorter than ISER_HEADERS_LEN

A flaw was found in the Linux kernel's Internet Small Computer System Interface iSCSI Extensions for Remote Direct Memory Access RDMA iSER module. A remote attacker can send a specially crafted login request with a payload shorter than expected, leading to an integer underflow. This underflow...
