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

  - macvlan: fix macvlan_get_size() not reserving space for IFLA_MACVLAN_BC_CUTOFF macvlan_get_size() does not     account for IFLA_MACVLAN_BC_CUTOFF, but macvlan_fill_info() conditionally includes it when port->bc_cutoff     != 1. This causes nla_put_s32() to fail with -EMSGSIZE when the netlink skb runs out of space, triggering     a WARN_ON in rtnetlink and preventing the interface from being dumped. The bug can be reproduced with: ip     link add macvlan0 link eth0 type macvlan mode bridge ip link set macvlan0 type macvlan bc_cutoff 0 ip -d     link show macvlan0 # fails with -EMSGSIZE The bc_cutoff feature was added in commit 954d1fa1ac93     (macvlan: Add netlink attribute for broadcast cutoff), which added the nla_put_s32() call in     macvlan_fill_info() but missed adding the corresponding nla_total_size(4) in macvlan_get_size(). A follow-     up commit 55cef78c244d (macvlan: add forgotten nla_policy for IFLA_MACVLAN_BC_CUTOFF) fixed the missing     nla_policy entry but still did not fix the size calculation. (CVE-2026-53013)

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