[Impact]
The two vulnerabilities affect nftables and allow an unprivileged user to
escalate privileges.

[Backport]
The 2 commits fix the same commit ID and apply cleanly of the affected series.

[Potential regression]
nftables users may regress.

Pablo Neira Ayuso (2):
  netfilter: nf_tables: skip bound chain on rule flush
  netfilter: nf_tables: disallow rule addition to bound chain via
    NFTA_RULE_CHAIN_ID
