If the packet destination did not change we may end up recording a reference to the lwtunnel in its own cache, and the lwtunnel state will never be freed.</p> <p>Discovered by the ioam6.sh test, kmemleak was recently fixed to catch per-cpu memory leaks. I&#39;m not sure if rpl and seg6 can actually hit this, but in principle I don&#39;t see why not.</p> <p><strong>Affected:</strong> Linux</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>net: ipv6: fix dst ref loops in rpl, seg6 and ioam6 lwtunnels</p> <p>Some lwtunnels have a dst cache for post-transformation dst.
