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: ice: Fix deinitializing VF in error     path If ice_ena_vfs() fails after calling ice_create_vf_entries(), it frees all VFs without removing them     from snapshot PF-VF mailbox list, leading to list corruption. Reproducer: devlink dev eswitch set $PF1_PCI     mode switchdev ip l s $PF1 up ip l s $PF1 promisc on sleep 1 echo 1 >     /sys/class/net/$PF1/device/sriov_numvfs sleep 1 echo 1 > /sys/class/net/$PF1/device/sriov_numvfs Trace     (minimized): list_add corruption. next->prev should be prev (ffff8882e241c6f0), but was 0000000000000000.
    (next=ffff888455da1330). kernel BUG at lib/list_debug.c:29! RIP:

    __list_add_valid_or_report+0xf1/0x100 VFs are added to this list in ice_mbx_init_vf_info(), but only     removed in ice_free_vfs(). Move the removing to ice_free_vf_entries(), which is also being called in other     places where VFs are being removed (including ice_free_vfs() itself). (CVE-2025-21883)

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