Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to a refcount leak in the probe function of the rk817 component in the Linux kernel. This leak was identified by the Smatch static checker warning. The problem arises because of node put() was only added in one of the return paths, but it should be added for all return paths that return an error and at driver removal time. This could potentially allow an attacker to cause a denial of service.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
