A vulnerability has been identified in Linux Kernel, which could be exploited by local attackers to cause a denial of service. This flaw is due to an infinite loop error in the "ip6fl_get_n()" [net/ipv6/ip6_flowlabel.c] function when handling seqfiles for "/proc/net/ip6_flowlabel", which could be exploited by malicious users to crash an affected system, creating a denial of service condition.
