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-2026-90413

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-2026-90293

CVE-2026-90293 is a NULL pointer dereference in the Linux kernel's IB/isert (iSCSI target over RDMA) component. The function isert_put_login_tx() posts full-feature receive buffers before __transport_register_session() completes, so an iSCSI initiator that sends a SCSI command before receiving th...

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...

CVE-2026-53176

CVE-2026-53176 affects the Linux kernel iSER (IB/isert) login handling in ib_isert.c. A remote iSER initiator could send a login PDU shorter than ISER_HEADERS_LEN (76), causing an integer underflow in isert_login_recv_done() when computing login_req_len, leading to a negative length used in a mem...
