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

  - tty: Fix out-of-bound vmalloc access in imageblit This issue happens when a userspace program does an     ioctl FBIOPUT_VSCREENINFO passing the fb_var_screeninfo struct containing only the fields xres, yres, and     bits_per_pixel with values. If this struct is the same as the previous ioctl, the vc_resize() detects it     and doesn't call the resize_screen(), leaving the fb_var_screeninfo incomplete. And this leads to the     updatescrollmode() calculates a wrong value to fbcon_display->vrows, which makes the real_y() return a     wrong value of y, and that value, eventually, causes the imageblit to access an out-of-bound address     value. To solve this issue I made the resize_screen() be called even if the screen does not need any     resizing, so it will fix and fill the fb_var_screeninfo independently. (CVE-2021-47383)

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