Description

The vulnerability allows a remote non-authenticated attacker to perform a denial of service (DoS) attack.

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.


Remediation

Install update from vendor's website.
