Summary
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.

"value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: cxgb4: Se corrige la fuga de memoria en la ruta de error de cxgb4_init_ethtool_filters(). En el bucle for utilizado para asignar loc_array y bmap para cada puerto, es posible que se produzca una fuga de memoria cuando la asignaci\u00f3n de loc_array se realiza correctamente, pero la de bmap falla. Esto se debe a que, cuando el flujo de control accede a la etiqueta free_eth_finfo, solo se liberan las asignaciones a partir de la iteraci\u00f3n (i-1). Para solucionar esto, libere loc_array en la ruta de error de asignaci\u00f3n de bmap."
