CVE-2021-47624

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

Description The issue is related to a reference count leak in the rpc sysfs xprt state change function in the Linux kernel's sunrpc component. This leak occurs when the 3rd argument buf does not match with "offline", "online", or "remove", causing the function to return -EINVAL and forget to decrease the reference count of rpc xprt and rpc xprt switch objects. This can lead to reference count leaks of both unused objects. The issue can be exploited 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.
