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 possible infinite loop in
rt6_fill_node() Sashiko reported this issue [1]. Apply the same fix as commit f8d8ce1b515a ("ipv6: fix
possible infinite loop in fib6_info_uses_dev()"). Writers holding tb6_lock can
list_del_rcu(&rt->fib6_siblings) without waiting for RCU readers; rt->fib6_siblings.next then still points
into the old ring and this softirq-side walker never reaches &rt->fib6_siblings, causing a CPU stall.
fib6_del_route() always WRITE_ONCE()s rt->fib6_nsiblings to 0 before list_del_rcu(), so an inside-loop
check is a reliable detach signal. [1]
