The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-010689 advisory.

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

    arch/arm64: Fix topology initialization for core scheduling

    Arm64 systems rely on store_cpu_topology() to call update_siblings_masks()     to transfer the toplogy to the various cpu masks. This needs to be done     before the call to notify_cpu_starting() which tells the scheduler about     each cpu found, otherwise the core scheduling data structures are setup     in a way that does not match the actual topology.

    With smt_mask not setup correctly we bail on `cpumask_weight(smt_mask) == 1`     for !leaders in:

     notify_cpu_starting()        cpuhp_invoke_callback_range()          sched_cpu_starting()            sched_core_cpu_starting()

    which leads to rq->core not being correctly set for !leader-rq's.

    Without this change stress-ng (which enables core scheduling in its prctl     tests in newer versions -- i.e. with PR_SCHED_CORE support) causes a warning     and then a crash (trimmed for legibility):
