"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/sunrpc: fix reference count leaks in rpc_sysfs_xprt_state_change\n\nThe refcount leak issues take place in an error handling path. When the\n3rd argument buf doesn't match with \"offline\", \"online\" or \"remove\", the\nfunction simply returns -EINVAL and forgets to decrease the reference\ncount of a rpc_xprt object and a rpc_xprt_switch object increased by\nrpc_sysfs_xprt_kobj_get_xprt() and\nrpc_sysfs_xprt_kobj_get_xprt_switch(), causing reference count leaks of\nboth unused objects.\n\nFix this issue by jumping to the error handling path labelled with\nout_put when buf matches none of \"offline\", \"online\" or \"remove\"."
