Unity Linux 20.1070e Security Update: kernel (UTSA-2025-987181)

medium Nessus Plugin ID 267999

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-2025-987181 advisory.

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

 iommu/arm-smmu: fix possible null-ptr-deref in arm_smmu_device_probe()

 It will cause null-ptr-deref when using 'res', if platform_get_resource() returns NULL, so move using 'res' after devm_ioremap_resource() that will check it to avoid null-ptr-deref.
 And use devm_platform_get_and_ioremap_resource() to simplify code.

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.
