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-2025-992849 advisory.

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

powercap: intel_rapl: fix UBSAN shift-out-of-bounds issue

When value < time_unit, the parameter of ilog2() will be zero and the return value is -1. u64(-1) is too large for shift exponent and then will trigger shift-out-of-bounds:

shift exponent 18446744073709551615 is too large for 32-bit type 'int' Call Trace:
rapl_compute_time_window_core rapl_write_data_raw set_time_window store_constraint_time_window_us

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.
