Summary
The rt6_fill_node function in net/ipv6/route.c in Linux kernel 2.6.26-rc4, 2.6.26.2, and possibly other 2.6.26 versions, allows local users to cause a denial of service (kernel OOPS) via IPv6 requests when no IPv6 input device is in use, which triggers a NULL pointer dereference.
Exploit prediction
0.47% chance of exploitation in the next 30 days, higher than 41% of all scored CVEs (FIRST EPSS, 2026-11-08).
