CVE-2026-89790

CVE-2026-89790 is a divide-by-zero vulnerability in the Linux kernel IPv6 routing code, specifically in rt6_multipath_rebalance() (net/ipv6/route.c). Because RTM_NEWROUTE operates without the RTNL lock, a concurrent update to ignore_routes_with_linkdown can cause the first pass to compute a zero ...
