"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2025-407641 advisory.

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

    RDMA/hns: Fix spin_unlock_irqrestore() called with IRQs enabled

    Fix missuse of spin_lock_irq()/spin_unlock_irq() when
    spin_lock_irqsave()/spin_lock_irqrestore() was hold.

    This was discovered through the lock debugging, and the corresponding
    log is as follows:

    raw_local_irq_restore() called with IRQs enabled
