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

  - of: check previous kernel's ima-kexec-buffer against memory bounds Presently ima_get_kexec_buffer()     doesn't check if the previous kernel's ima-kexec-buffer lies outside the addressable memory range. This     can result in a kernel panic if the new kernel is booted with 'mem=X' arg and the ima-kexec-buffer was     allocated beyond that range by the previous kernel. The panic is usually of the form below: $ sudo kexec
