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: netfilter: nf_nat: avoid invalid
nat_net pointer use on failed nf_nat_init() We ran into below KASAN splat, which is mostly uninteresting,
beside for having nf_nat_register_fn() in the call chain as a cause for the offending access:
