"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2026-007367 advisory.

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

    clk: qcom: ipq8074: dont disable gcc_sleep_clk_src

    Once the usb sleep clocks are disabled, clock framework is trying to
    disable the sleep clock source also.

    However, it seems that it cannot be disabled and trying to do so produces:

    So, add CLK_IS_CRITICAL flag to the clock so that the kernel won't try
    to disable the sleep clock.
