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...
