In the Linux kernel, the following vulnerability has been resolved: mm/uffd: fix warning without PTE_MARKER_UFFD_WP compiled in When PTE_MARKER_UFFD_WP not configured, it's still possible to reach pte marker code and trigger an warning. Add a few CONFIG_PTE_MARKER_UFFD_WP ifdefs to make sure the code won't be reached when not compiled in.
