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

ipv4: route: Prevent rtbindexception() from rebinding stale fnhe

The sit driver's packet transmission path calls: sittunnelxmit() -> updateorcreatefnhe(), which lead to fnheremoveoldest() being called to delete entries exceeding FNHERECLAIMDEPTH+random.

The race window is between fnheremoveoldest() selecting fnheX for deletion and the subsequent kfreercu(). During this time, the concurrent path's mkrouteoutput() -> findexception() can fetch the soon-to-be-deleted fnheX, and rtbindexception() then binds it with a new dst using a dsthold(). When the original fnheX is freed via RCU, the dst reference remains permanently leaked.

CPU 0 CPU 1 mkrouteoutput() findexception() [fnheX] updateorcreatefnhe() fnheremoveoldest() [fnheX] rtbindexception() [bind dst] RCU callback [fnheX freed, dst leak]

This issue manifests as a device reference count leak and a warning in dmesg when unregistering the net device:

unregisternetdevice: waiting for sitX to become free. Usage count = N

Ido Schimmel provided the simple test validation method [1].

The fix clears 'oldest->fnhedaddr' before calling fnheflushroutes(). Since rtbindexception() checks this field, setting it to zero prevents the stale fnhe from being reused and bound to a new dst just before it is freed.
