Unity Linux 20.1050a / 20.1060a / 20.1070a Security Update: kernel (UTSA-2025-402337)

medium Nessus Plugin ID 267108

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-2025-402337 advisory.

In the Linux kernel, the following vulnerability has been resolved:

vt: fix unicode buffer corruption when deleting characters

This is the same issue that was fixed for the VGA text buffer in commit 39cdb68c64d8 (vt: fix memory overlapping when deleting chars in the buffer). The cure is also the same i.e. replace memcpy() with memmove() due to the overlaping buffers.

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.
