Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2026-003025)

high Nessus Plugin ID 287432

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-2026-003025 advisory.

drivers/media/v4l2-core/videobuf2-v4l2.c in the Linux kernel before 4.5.3 allows local users to cause a denial of service (kernel memory write operation) or possibly have unspecified other impact via a crafted number of planes in a VIDIOC_DQBUF 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.
