7.1 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H

Details

In the Linux kernel, the following vulnerability has been resolved:

net/sunrpc: fix reference count leaks in rpc_sysfs_xprt_state_change

The refcount leak issues take place in an error handling path. When the 3rd argument buf doesn't match with "offline", "online" or "remove", the function simply returns -EINVAL and forgets to decrease the reference count of a rpc_xprt object and a rpc_xprt_switch object increased by rpc_sysfs_xprt_kobj_get_xprt() and rpc_sysfs_xprt_kobj_get_xprt_switch(), causing reference count leaks of both unused objects.

Fix this issue by jumping to the error handling path labelled with out_put when buf matches none of "offline", "online" or "remove".
