Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: ipv6: Fix a potential NPD in
 cleanup_prefix_route() addrconf_get_prefix_route() can return the fib6_null_entry sentinel entry which has
 a NULL fib6_table pointer. Therefore, before setting the route's expiration time, check that we are not
 working with this entry, as otherwise a NPD will be triggered [1]. Note that the other callers of
 addrconf_get_prefix_route() are not susceptible to this bug: 1. addrconf_prefix_rcv(): Requests a route
 with the 'RTF_ADDRCONF | RTF_PREFIX_RT' flags which are not set on fib6_null_entry. 2.
 modify_prefix_route(): Fixed by commit a747e02430df ("ipv6: avoid possible NULL deref in
 modify_prefix_route()"). 3. __ipv6_ifa_notify(): Calls ip6_del_rt() which specifically checks for
 fib6_null_entry and returns an error. [1] Oops: general protection fault, probably for non-canonical
