  "details": "In the Linux kernel, the following vulnerability has been resolved:  scsi: qla2xxx: edif: Fix NULL pointer deref in RX SA delete check  qla_chk_edif_rx_sa_delete_pending() obtains the SCSI command via GET_CMD_SP(sp) and immediately dereferences cmd-\u003esc_data_direction. That command pointer can be NULL: the firmware may post a status completion for a command that has already been returned or aborted.  The caller qla2x00_status_entry() acknowledges this on the very same status path, re-fetching GET_CMD_SP(sp) and bailing out with the \"Command already returned\" message when it is NULL -- but that check runs only after qla_chk_edif_rx_sa_delete_pending() has already dereferenced the pointer, so a NULL cmd crashes the kernel in interrupt context.  Return early when cmd is NULL, before touching cmd-\u003esc_data_direction.",
