Nutanix AHV : (NXSA-AHV-10.3.1.8)

high Nessus Plugin ID 325929

Synopsis

The Nutanix AHV host is affected by a vulnerability.

Description

The version of AHV installed on the remote host is prior to 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.

Solution

Update the Nutanix AHV software to the recommended version. Before upgrading: if this cluster is registered with Prism Central, ensure that Prism Central has been upgraded first to a compatible version. Refer to the Software Product Interoperability page on the Nutanix portal.
