The first\nthing on that path, qla_chk_edif_rx_sa_delete_pending(), and the\nsubsequent handling both evaluate GET_CMD_SP(sp), i.e. sp->u.scmd.cmd.\n\nThe srb u union overlays the SCSI command pointer with other command\nlayouts (bsg_job, iocb_cmd). If firmware delivers an unexpected\nSTATUS_TYPE IOCB for a non-SCSI handle, sp->u.scmd.cmd can read as a\nnon-NULL garbage pointer, bypassing the NULL checks in\nqla_chk_edif_rx_sa_delete_pending() and at the cp == NULL test, and\nleading to a wild pointer dereference.\n\nReject any SRB whose type is not SRB_SCSI_CMD before entering the fast\npath. The outstanding_cmds slot is left untouched so a genuinely\nnon-SCSI command still completes through its proper handler.","state":0,"publishedAt":"2026-09-16T10:31:23.18+00:00","modifiedAt":"2026-10-19T08:53:42.181+00:00","affected":[{"ecosystem":"Vendor
