Unity Linux 20.1070a Security Update: kernel (UTSA-2025-989603)

low Nessus Plugin ID 273438

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-2025-989603 advisory.

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

 dmaengine: ti: k3-udma-private: Fix refcount leak bug in of_xudma_dev_get()

 We should call of_node_put() for the reference returned by of_parse_phandle() in fail path or when it is not used anymore.
 Here we only need to move the of_node_put() before the check.

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.
