Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-992486)

medium Nessus Plugin ID 280176

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-2025-992486 advisory.

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

 drm/radeon: Add the missed acpi_put_table() to fix memory leak

 When the radeon driver reads the bios information from ACPI table in radeon_acpi_vfct_bios(), it misses to call acpi_put_table() to release the ACPI memory after the init, so add acpi_put_table() properly to fix the memory leak.

 v2: fix text formatting (Alex)

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.
