Unity Linux 20.1070a Security Update: kernel (UTSA-2025-990236)

high Nessus Plugin ID 272590

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-2025-990236 advisory.

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

net: mdio: validate parameter addr in mdiobus_get_phy()

The caller may pass any value as addr, what may result in an out-of-bounds access to array mdio_map. One existing case is stmmac_init_phy() that may pass -1 as addr. Therefore validate addr before using it.

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.
