Unity Linux 20.1060e / 20.1070e Security Update: kernel (UTSA-2025-992661)

medium Nessus Plugin ID 280669

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-2025-992661 advisory.

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

 acpi: nfit: fix narrowing conversion in acpi_nfit_ctl

 Syzkaller has reported a warning in to_nfit_bus_uuid(): only secondary bus families can be translated. This warning is emited if the argument is equal to NVDIMM_BUS_FAMILY_NFIT == 0. Function acpi_nfit_ctl() first verifies that a user-provided value call_pkg->nd_family of type u64 is not equal to 0. Then the value is converted to int, and only after that is compared to NVDIMM_BUS_FAMILY_MAX. This can lead to passing an invalid argument to acpi_nfit_ctl(), if call_pkg->nd_family is non-zero, while the lower 32 bits are zero.

 Furthermore, it is best to return EINVAL immediately upon seeing the invalid user input. The WARNING is insufficient to prevent further undefined behavior based on other invalid user input.

 All checks of the input value should be applied to the original variable call_pkg->nd_family.

 [iweiny: update commit message]

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.
