Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-011217)

low Nessus Plugin ID 308497

Synopsis

The Unity Linux host is missing one or more security updates.

Description

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-011217 advisory.

In the Linux kernel, the following vulnerability has been resolved:

xfrm/compat: prevent potential spectre v1 gadget in xfrm_xlate32_attr()

int type = nla_type(nla);

if (type > XFRMA_MAX) { return -EOPNOTSUPP;
}

@type is then used as an array index and can be used as a Spectre v1 gadget.

if (nla_len(nla) < compat_policy[type].len) {

array_index_nospec() can be used to prevent leaking content of kernel memory to malicious users.

Tenable has extracted the preceding description block directly from the Unity Linux security advisory.

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 affected kernel package.
