Unity Linux 20.1070e Security Update: kernel (UTSA-2025-986846)

medium Nessus Plugin ID 267984

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-2025-986846 advisory.

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

 gpio: amd8111: Fix PCI device reference count leak

 for_each_pci_dev() is implemented by pci_get_device(). The comment of pci_get_device() says that it will increase the reference count for the returned pci_dev and also decrease the reference count for the input pci_dev @from if it is not NULL.

 If we break for_each_pci_dev() loop with pdev not NULL, we need to call pci_dev_put() to decrease the reference count. Add the missing pci_dev_put() after the 'out' label. Since pci_dev_put() can handle NULL input parameter, there is no problem for the 'Device not found' branch.
 For the normal path, add pci_dev_put() in amd_gpio_exit().

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.
