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

  - crypto: ccp - Use kzalloc for sev ioctl interfaces to prevent kernel memory leak For some sev ioctl     interfaces, input may be passed that is less than or equal to SEV_FW_BLOB_MAX_SIZE, but larger than the     data that PSP firmware returns. In this case, kmalloc will allocate memory that is the size of the input     rather than the size of the data. Since PSP firmware doesn't fully overwrite the buffer, the sev ioctl     interfaces with the issue may return uninitialized slab memory. Currently, all of the ioctl interfaces in     the ccp driver are safe, but to prevent future problems, change all ioctl interfaces that allocate memory     with kmalloc to use kzalloc and memset the data buffer to zero in sev_ioctl_do_platform_status.
    (CVE-2022-50226)

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