Description OSIDB Bzimport 2025-02-26 03:15:09 UTC
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.
