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->sc_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->sc_data_direction.
