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: net: better track kernel sockets
 lifetime While kernel sockets are dismantled during pernet_operations->exit(), their freeing can be
 delayed by any tx packets still held in qdisc or device queues, due to skb_set_owner_w() prior calls. This
 then trigger the following warning from ref_tracker_dir_exit() [1] To fix this, make sure that kernel
 sockets own a reference on net->passive. Add sk_net_refcnt_upgrade() helper, used whenever a kernel socket
 is converted to a refcounted one. [1] [ 136.263918][ T35] ref_tracker: net notrefcnt@ffff8880638f01e0 has
