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: ipmr: do not call mr_mfc_uses_dev()     for unres entries syzbot found that calling mr_mfc_uses_dev() for unres entries would crash [1], because     c->mfc_un.res.minvif / c->mfc_un.res.maxvif alias to struct sk_buff_head unresolved, which contain two     pointers. This code never worked, lets remove it.
