"The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the
UTSA-2025-993303 advisory.

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

    scsi: qla2xxx: Perform lockless command completion in abort path

    While adding and removing the controller, the following call trace was
    observed:

    The command was completed in the abort path during driver unload with a
    lock held, causing the warning in abort path. Hence complete the command
    without any lock held.
