CVE-2026-23300

A flaw was found in the Linux kernel's IPv6 networking stack. When a standalone IPv6 nexthop object is created with a loopback device, it is misclassified as a reject route, leading to an unallocated pointer. If an IPv4 route then attempts to reference this nexthop, it causes a NULL pointer...

CVE-2009-0778

CVE-2009-0778 affects the Linux kernel prior to 2.6.25 when configured as a router with a REJECT route. The icmp_send code in net/ipv4/icmp.c can mishandle the Protocol Independent Destination (DST) cache, potentially leaking DST state and allowing remote attackers to cause a denial of service (c...
