CVE-2022-49213

In the Linux kernel, the following vulnerability has been resolved: ath10k: Fix error handling in ath10k_setup_msa_resources 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 path.

Summary		(es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: ath10k: Se ha corregido la gestión de errores en ath10k_setup_msa_resources 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 normal. Y provocará una fuga de refcount en la ruta de error.
