Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2026-002086)

critical Nessus Plugin ID 286438

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-2026-002086 advisory.

Use-after-free vulnerability in the kvm_ioctl_create_device function in virt/kvm/kvm_main.c in the Linux kernel before 4.8.13 allows host OS users to cause a denial of service (host OS crash) or possibly gain privileges via crafted ioctl calls on the /dev/kvm device.

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.
