In the Linux kernel, the following vulnerability has been resolved: crypto: virtio - bound the akcipher result length virtio_crypto_dataq_akcipher_callback() sets the result length from the device-reported response length without bounding it to the destination buffer, which was allocated for the original request length. sg_copy_from_buffer() then reads that many bytes from the destination buffer; a backend reporting a larger length over-reads adjacent kernel heap into the caller's scatterlist (an out-of-bounds read). Clamp the reported length to the originally requested destination length. A conforming device reports no more than that, so valid results are unaffected.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

    result length virtio_crypto_dataq_akcipher_callback() sets the result length from the device-reported
    response length without bounding it to the destination buffer, which was allocated for the original

    read). Clamp the reported length to the originally requested destination length. A conforming device
    reports no more than that, so valid results are unaffected. (CVE-2026-80836)

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

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