CVE-2026-99070
Beschrijving NL
In the Linux kernel, the following vulnerability has been resolved:
ipv6: do not warn on route notification size race
fib6_info_hw_flags_set() sizes the skb with rt6_nlmsg_size() and later
fills it with rt6_fill_node(). With nexthop compatibility mode enabled,
a concurrent replacement can grow the group between these independent
snapshots. rt6_fill_node() can then legitimately return -EMSGSIZE, so
the warning does not prove a sizing bug. Remove the warning. The existing error path still frees the skb and
reports the error to listeners.
