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.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-007358 advisory.

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

    UM: cpuinfo: Fix a warning for CONFIG_CPUMASK_OFFSTACK

    When CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS is selected,     cpu_max_bits_warn() generates a runtime warning similar as below while     we show /proc/cpuinfo. Fix this by using nr_cpu_ids (the runtime limit)     instead of NR_CPUS to iterate CPUs.
