- Summary
- ASoC: audio-graph-card: fix refcount leak of cpu_ep in __graph_for_each_link()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
ASoC: audio-graph-card: fix refcount leak of cpu_ep in _graphforeachlink()
The ofgetnextchild() returns a node with refcount incremented, and decrements the refcount of prev. So in the error path of the while loop, ofnodeput() needs be called for cpuep.
