"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2025-990357 advisory.

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

    tracing: Build event generation tests only as modules

    The kprobes and synth event generation test modules add events and lock
    (get a reference) those event file reference in module init function,
    and unlock and delete it in module exit function. This is because those
    are designed for playing as modules.

    If we make those modules as built-in, those events are left locked in the
    kernel, and never be removed. This causes kprobe event self-test failure
    as below.

    And also, since we can not cleanup dynamic_event file, ftracetest are
    failed too.

    To avoid these issues, build these tests only as modules.
