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.
