Unity Linux 20.1070a Security Update: kernel (UTSA-2025-990623)

medium Nessus Plugin ID 274239

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-2025-990623 advisory.

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

fbdev: savage: Handle err return when savagefb_check_var failed

The commit 04e5eac8f3ab(fbdev: savage: Error out if pixclock equals zero) checks the value of pixclock to avoid divide-by-zero error. However the function savagefb_probe doesn't handle the error return of savagefb_check_var. When pixclock is 0, it will cause divide-by-zero error.

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.
