Описание
In the Linux kernel, the following vulnerability has been resolved:
remoteproc: qcom_q6v5_mss: Fix some leaks in q6v5_alloc_memory_region
The device_node pointer is returned by of_parse_phandle() or
of_get_child_by_name() with refcount incremented.
We should use of_node_put() on it when done.
This function only call of_node_put(node) when of_address_to_resource
succeeds, missing error cases.
A flaw was found in the qcom_q6v5_mss module in the Linux kernel. A memory leak can occur when allocated memory is not released in certain error cases, potentially impacting system performance and resulting in a denial of service.
