Title
ASoC: audio-graph-card: fix refcount leak of cpu_ep in __graph_for_each_link()
Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: audio-graph-card: fix refcount leak of cpu_ep in __graph_for_each_link()
The of_get_next_child() returns a node with refcount incremented, and
decrements the refcount of prev. So in the error path of the while loop,
of_node_put() needs be called for cpu_ep.
Severity
No CVSS data available.
