Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
netfilter: ip6t_rt: reject oversized addrnr in rt_mt6_check()<br />
<br />
Reject rt match rules whose addrnr exceeds IP6T_RT_HOPS.<br />
<br />
rt_mt6() expects addrnr to stay within the bounds of rtinfo->addrs[].<br />
Validate addrnr during rule installation so malformed rules are rejected<br />
before the match logic can use an out-of-range value.
Impacto
