In the Linux kernel, the following vulnerability has been resolved:

scsi: qla2xxx: Reject non-SCSI SRB on status IOCB fast path

qla2x00_status_entry() filters out non-TYPE_SRB entries and the SRB_NVME_CMD, SRB_BIDI_CMD and SRB_TM_CMD types, then falls through to a SCSI fast path that assumes the command is an SRB_SCSI_CMD. The first thing on that path, qla_chk_edif_rx_sa_delete_pending(), and the subsequent handling both evaluate GET_CMD_SP(sp), i.e. sp->u.scmd.cmd.

The srb u union overlays the SCSI command pointer with other command layouts (bsg_job, iocb_cmd). If firmware delivers an unexpected STATUS_TYPE IOCB for a non-SCSI handle, sp->u.scmd.cmd can read as a non-NULL garbage pointer, bypassing the NULL checks in qla_chk_edif_rx_sa_delete_pending() and at the cp == NULL test, and leading to a wild pointer dereference.

Reject any SRB whose type is not SRB_SCSI_CMD before entering the fast path. The outstanding_cmds slot is left untouched so a genuinely non-SCSI command still completes through its proper handler.

No fix is confirmed yet. Restrict network exposure of the affected system or apply the vendor's mitigation within your standard update timelines at low or medium mission impact and sooner than that at high, and watch the vendor's advisory for the fix.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
