Description

NetBSD's sys/netinet6/udp6_output.c udp6_output() function contains a flaw that may allow a local denial of service. The issue is triggered when bad parameters are passed to the "opt" variable that is used to store IPv6 packet options. This can result in udp6_output() releasing the options without creating them first and leading to an uninitialized pointer access, which may result in loss of availability for the platform.
