This vulnerability has been modified since it was last analyzed by the NVD. It is awaiting reanalysis which may result in further changes to the information provided.
The ip6_dst_lookup_tail function in net/ipv6/ip6_output.c in the Linux kernel before 2.6.27 does not properly handle certain circumstances involving an IPv6 TUN network interface and a large number of neighbors, which allows attackers to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact via unknown vectors.

Red Hat is aware of this issue and is tracking it via the following bug:
This issue did not affect the versions of Linux kernel as shipped with Red Hat Enterprise Linux 3 and 4, as they do not include support for Optimistic Duplicate Address Detection (DAD) in IPv6. This was addressed in Red Hat Enterprise Linux 5 via https://rhn.redhat.com/errata/RHSA-2010-9419.html. A future update in Red Hat Enterprise MRG may address this flaw.
