In the Linux kernel, the following vulnerability has been resolved: netfilter: ebtables: move to two-stage removal scheme Like previous patches for x_tables, follow same pattern in ebtables. We can't reuse xt helpers: ebt_table struct layout is incompatible. table->ops assignment is now done while still holding the ebt mutex to make sure we never expose partially-filled table struct.

An update of the linux package has been released.

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

  - netfilter: ebtables: move to two-stage removal scheme Like previous patches for x_tables, follow same     pattern in ebtables. We can't reuse xt helpers: ebt_table struct layout is incompatible. table->ops     assignment is now done while still holding the ebt mutex to make sure we never expose partially-filled     table struct. (CVE-2026-64077)

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