Descriptions
In the Linux kernel, the following vulnerability has been resolved:
of: Fix double free in of_parse_phandle_with_args_map
In of_parse_phandle_with_args_map() the inner loop that
iterates through the map entries calls of_node_put(new)
to free the reference acquired by the previous iteration
of the inner loop. This assumes that the value of "new" is
NULL on the first iteration of the inner loop.
Make sure that this is true in all iterations of the outer
loop by setting "new" to NULL after its value is assigned to "cur".
Extend the unittest to detect the double free and add an additional
test case that actually triggers this path.
En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: of: Solucionado double free en of_parse_phandle_with_args_map En of_parse_phandle_with_args_map() el bucle interno que itera por las entradas del mapa llama a of_node_put(new) para liberar la referencia adquirida por la iteración anterior del bucle interno . Esto supone que el valor de "nuevo" es NULL en la primera iteración del bucle interno. Asegúrese de que esto sea cierto en todas las iteraciones del bucle externo estableciendo "nuevo" en NULL después de que su valor se asigne a "cur". Amplíe la prueba unitaria para detectar el doble free y agregue un caso de prueba adicional que realmente active esta ruta.
