Summary
netfilter: ip6t_rt: reject oversized addrnr in rt_mt6_check()
Details

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

netfilter: ip6trt: reject oversized addrnr in rtmt6_check()

Reject rt match rules whose addrnr exceeds IP6TRTHOPS.

rt_mt6() expects addrnr to stay within the bounds of rtinfo->addrs[]. Validate addrnr during rule installation so malformed rules are rejected before the match logic can use an out-of-range value.
