Linux kernel is vulnerable to improper input validation attacks. This occurs in the ip6_append_data function in net/ipv6/ip6_output.c because it is too late in checking whether an overwrite of an skb data structure may occur. An attacker could cause an application crash resulting in denial of service condition.
