CVE-2026-74557

CVE-2026-74557 (Linux kernel) affects the SCSI/libiscsi path. The bug occurs in iscsi_scsi_cmd_rsp(): it copies sense data from a target-provided segment that starts with a 2-byte sense length, but the bounds check only verified datalen against senselen. As a result, when datalen equals senselen ...
