In the Linux kernel, the following vulnerability has been resolved: net/sched: act_ct: fix ref leak when switching zones When switching zones or network namespaces without doing a ct clear in between, it is now leaking a reference to the old ct entry. That's because tcf_ct_skb_nfct_cached() returns false and tcf_ct_flow_table_lookup() may simply overwrite it. The fix is to, as the ct entry is not reusable, free it already at tcf_ct_skb_nfct_cached().

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-4664 advisory.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: net/sched: act_ct: fix ref leak when     switching zones When switching zones or network namespaces without doing a ct clear in between, it is now     leaking a reference to the old ct entry.

Note that Nessus relies on the presence of the package as reported by the vendor.
