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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":48,"depthScoreParts":{"impact":48.4,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[{"seq":205190,"id":"CVE-2026-89849","ts":1789570705655,"field":"cvss","old":null,"new":"8.8"},{"seq":205189,"id":"CVE-2026-89849","ts":1789570705655,"field":"severity","old":"none","new":"high"}]}
