    After enabling CONFIG_SCHED_CORE (landed during 5.14 cycle),     2-core 2-thread-per-core interAptiv (CPS-driven) started emitting     the following:

    Basic debug printks right before the mentioned line say:

    [    0.048170] CPU: 1, smt_mask:

    So smt_mask, which is sibling mask obviously, is empty when entering     the function.
    This is critical, as sched_core_cpu_starting() calculates     core-scheduling parameters only once per CPU start, and it's crucial     to have all the parameters filled in at that moment (at least it     uses cpu_smt_mask() which in fact is `&cpu_sibling_map[cpu]` on     MIPS).

    A bit of debugging led me to that set_cpu_sibling_map() performing     the actual map calculation, was being invocated after     notify_cpu_start(), and exactly the latter function starts CPU HP     callback round (sched_core_cpu_starting() is basically a CPU HP     callback).
    While the flow is same on ARM64 (maps after the notifier, although     before calling set_cpu_online()), x86 started calculating sibling     maps earlier than starting the CPU HP callbacks in Linux 4.14 (see     [0] for the reference). Neither me nor my brief tests couldn't find     any potential caveats in calculating the maps right after performing     delay calibration, but the WARN splat is now gone.
    The very same debug prints now yield exactly what I expected from     them:

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

An update of the linux package has been released.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-986583 advisory.
