      "title": "netfilter: ip6t_rt: fix zero-address non-strict match out-of-bounds read",
      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nnetfilter: ip6t_rt: fix zero-address non-strict match out-of-bounds read\n\nrt_mt6_check() permits rules to be configured with rtinfo->addrnr == 0\neven when address matching (IP6T_RT_FST_MASK) is requested.\n\nIn the IP6T_RT_FST_NSTRICT path, rt_mt6() evaluates packet routing\naddresses against rtinfo->addrs[i] and terminates backwards at the bottom\nof the loop:\n\n    if (ipv6_addr_equal(ap, &rtinfo->addrs[i])) {\n        i++;\n    }\n    if (i == rtinfo->addrnr)\n        break;\n\nWhen addrnr is 0, if the first packet address matches rtinfo->addrs[0],\ni is incremented to 1. Because i is now strictly greater than addrnr (0),\nthe loop termination condition (i == rtinfo->addrnr) is bypassed and will\nnever be satisfied.\n\nIf a crafted IPv6 packet contains matching routing addresses, i will\nadvance past IP6T_RT_HOPS (16). The subsequent call to ipv6_addr_equal()\nreads beyond struct ip6t_rt, triggering UBSAN/KASAN out-of-bounds warnings\nor kernel panics.\n\nFix this by:\n1. Rejecting rules in rt_mt6_check() where IP6T_RT_FST_MASK is set but\n   rtinfo->addrnr is zero.\n2. In rt_mt6(), moving the termination condition (i < rtinfo->addrnr)\n   into the for-loop header condition and removing the backwards break\n   at the end of the loop body.",
