Description
In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
net/sunrpc: fix reference count leaks in rpc_sysfs_xprt_state_change<br />
<br />
The refcount leak issues take place in an error handling path. When the<br />
3rd argument buf doesn&#39;t match with "offline", "online" or "remove", the<br />
function simply returns -EINVAL and forgets to decrease the reference<br />
count of a rpc_xprt object and a rpc_xprt_switch object increased by<br />
rpc_sysfs_xprt_kobj_get_xprt() and<br />
rpc_sysfs_xprt_kobj_get_xprt_switch(), causing reference count leaks of<br />
both unused objects.<br />
<br />
Fix this issue by jumping to the error handling path labelled with<br />
out_put when buf matches none of "offline", "online" or "remove".
