Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-001040)

high Nessus Plugin ID 291072

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-2026-001040 advisory.

The raw_cmd_copyin function in drivers/block/floppy.c in the Linux kernel through 3.14.3 does not properly handle error conditions during processing of an FDRAWCMD ioctl call, which allows local users to trigger kfree operations and gain privileges by leveraging write access to a /dev/fd 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.
