Unity Linux 20.1060a / 20.1070a Security Update: kernel (UTSA-2026-003278)

medium Nessus Plugin ID 287922

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-2026-003278 advisory.

The klsi_105_get_line_state function in drivers/usb/serial/kl5kusb105.c in the Linux kernel before 4.9.5 places uninitialized heap-memory contents into a log entry upon a failure to read the line status, which allows local users to obtain sensitive information by reading the log.

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.
