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

bnxt_en: set backing store type from query type

bnxt_hwrm_func_backing_store_qcaps_v2() stores resp->type from the
firmware response in ctxm->type and later uses that value to index
fixed backing-store metadata arrays such as ctx_arr[] and
bnxt_bstore_to_trace[].

ctxm->type is fixed by the current backing-store query type and matches
the array index of ctx->ctx_arr. Set ctxm->type from the current loop
variable instead of depending on resp->type.

Also update the loop to advance type from next_valid_type in the for
statement, which keeps the control flow simpler for non-valid and
unchanged entries.
