Base vector

AV:A/AC:H/Au:N/C:P/I:N/A:P

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 3.8

Description The issue arises from the improper handling of IPv6 temporary address generation, allowing remote attackers to cause a denial of service and potentially obtain sensitive information. This can be achieved by sending specific ICMPv6 Router Advertisement messages to the router, which can disable the creation of temporary addresses.

Recommendations For Linux kernel versions prior to 3.8, consider disabling the ipv6 create tempaddr function as a temporary workaround until a patch is available. Restrict access to ICMPv6 Router Advertisement messages to minimize the risk of exploitation. Update to a version 3.8 or later to resolve the issue.
