In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
net: gso: limit recursive IP-in-IP segmentation<\/p>\n
IP-in-IP GSO can re-enter inet_gso_segment() or ipv6_gso_segment()
\nfor each nested IP header. encap_level tracks header bytes, not callback
\ndepth, so a deep chain can exhaust the kernel stack. Making
\ninet_gso_segment() stackable introduced unbounded IPv4 nesting; IPIP
\nGSO\/TSO later made the path reachable. The IPv6 stackable path was
\nintroduced separately and uses the same guard.<\/p>\n
Count IPv4 and IPv6 GSO handler entries in skb_gso_cb, initialized once
\nper top-level GSO operation and preserved across GRE\/UDP context changes.
\nUse the existing IP_TUNNEL_RECURSION_LIMIT for both handlers. The first
\nfive entries pass, and the sixth returns -EINVAL before dispatching
\nanother GSO callback.<\/p>\n","protected":false},"excerpt":{"rendered":"
