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

    cxgb4: fix memory leak in cxgb4_init_ethtool_filters() error path

    In the for loop used to allocate the loc_array and bmap for each port, a
    memory leak is possible when the allocation for loc_array succeeds,
    but the allocation for bmap fails. This is because when the control flow
    goes to the label free_eth_finfo, only the allocations starting from
    (i-1)th iteration are freed.

    Fix that by freeing the loc_array in the bmap allocation error path.
