Unity Linux 20.1070a Security Update: kernel (UTSA-2025-990296)
medium Nessus Plugin ID 272617
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-2025-990296 advisory.In the Linux kernel, the following vulnerability has been resolved:
mfd: intel_soc_pmic_bxtwc: Use IRQ domain for USB Type-C device
While design wise the idea of converting the driver to use the hierarchy of the IRQ chips is correct, the implementation has (inherited) flaws. This was unveiled when platform_get_irq() had started WARN() on IRQ 0 that is supposed to be a Linux IRQ number (also known as vIRQ).
Rework the driver to respect IRQ domain when creating each MFD device separately, as the domain is not the same for all of them.
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.See Also
