Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2026-002148)

medium Nessus Plugin ID 286759

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-2026-002148 advisory.

The kvm_apic_has_events function in arch/x86/kvm/lapic.h in the Linux kernel through 4.1.3 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by leveraging /dev/kvm access for an ioctl call.

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.
