Unity Linux 20.1070a Security Update: kernel (UTSA-2025-989737)

high Nessus Plugin ID 273552

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-2025-989737 advisory.

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

phylib: fix potential use-after-free

Commit bafbdd527d56 (phylib: Add device reset GPIO support) added call to phy_device_reset(phydev) after the put_device() call in phy_detach().

The comment before the put_device() call says that the phydev might go away with put_device().

Fix potential use-after-free by calling phy_device_reset() before put_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.
