Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-992609)

medium Nessus Plugin ID 280616

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-2025-992609 advisory.

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

 virtio_net: fix memory leak inside XPD_TX with mergeable

 When we call xdp_convert_buff_to_frame() to get xdpf, if it returns NULL, we should check if xdp_page was allocated by xdp_linearize_page().
 If it is newly allocated, it should be freed here alone. Just like any other goto err_xdp.

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.
