"The version of AHV installed on the remote host is prior to 10.3.1.8 / AHV-10.3.1.8. It is, therefore, affected by a
vulnerability as referenced in the NXSA-AHV-10.3.1.8 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: crypto: algif_aead - Revert to
    operating out-of-place This mostly reverts commit 72548b093ee3 except for the copying of the associated
    data. There is no benefit in operating in-place in algif_aead since the source and destination come from
    different mappings. Get rid of all the complexity added for in-place operation and just copy the AD
    directly. (CVE-2026-31431)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
