"A use-after-free vulnerability was found in the Linux kernel's
netfilter subsystem in net/netfilter/nf_tables_api.c.  Mishandled
error handling with NFT_MSG_NEWRULE makes it possible to use a
dangling pointer in the same transaction causing a use-after-free
vulnerability. This flaw allows a local attacker with user access to
cause a privilege escalation issue.  We recommend upgrading past
commit1240eb93f0616b21c675416516ff3d74798fdc97.
