Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-992497)

medium Nessus Plugin ID 280687

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-2025-992497 advisory.

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

 i2c: mux: reg: check return value after calling platform_get_resource()

 It will cause null-ptr-deref in resource_size(), if platform_get_resource() returns NULL, move calling resource_size() after devm_ioremap_resource() that will check 'res' 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.

Solution

Update the affected kernel package.
