  3. CVE-2022-49161
In the Linux kernel, the following vulnerability has been resolved: ASoC: mediatek: Fix error handling in mt8183_da7219_max98357_dev_probe The device_node pointer is returned by of_parse_phandle() with refcount incremented. We should use of_node_put() on it when done. This function only calls of_node_put() in the regular path. And it will cause refcount leak in error paths. Fix this by calling of_node_put() in error handling too.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ASoC: mediatek: Se corrige la gestión de errores en mt8183_da7219_max98357_dev_probe El puntero device_node es devuelto por of_parse_phandle() con refcount incrementado. Deberíamos usar of_node_put() en él cuando haya terminado. Esta función solo llama a of_node_put() en la ruta regular. Y provocará una fuga de refcount en las rutas de error. Corrija esto llamando también a of_node_put() en la gestión de errores.
