CVE-2022-49183

CVE-2022-49183: Linux kernel net/sched act_ct had a ref-leak when switching zones or network namespaces without a ct clear, leaking the old ct entry due to tcf_ct_skb_nfct_cached() returning false. The fix is to free the ct entry at tcf_ct_skb_nfct_cached() since the ct entry is not reusable. Con...
