The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-993129 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.
