  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nbnxt_en: set backing store type from query type\n\nbnxt_hwrm_func_backing_store_qcaps_v2() stores resp-\u003etype from the\nfirmware response in ctxm-\u003etype and later uses that value to index\nfixed backing-store metadata arrays such as ctx_arr[] and\nbnxt_bstore_to_trace[].\n\nctxm-\u003etype is fixed by the current backing-store query type and matches\nthe array index of ctx-\u003ectx_arr. Set ctxm-\u003etype from the current loop\nvariable instead of depending on resp-\u003etype.\n\nAlso update the loop to advance type from next_valid_type in the for\nstatement, which keeps the control flow simpler for non-valid and\nunchanged entries.",
