The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-987532 advisory.

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

    powerpc/fixmap: Fix VM debug warning on unmap

    Unmapping a fixmap entry is done by calling __set_fixmap()     with FIXMAP_PAGE_CLEAR as flags.

    Today, powerpc __set_fixmap() calls map_kernel_page().

    map_kernel_page() is not happy when called a second time     for the same page.
