>:
>:If you do not think wine-preloader should need to mmap low memory in the kernel.

>:Do
>:contact your security administrator and report this issue.
>:
>:*****  Plugin catchall_boolean (42.6 confidence) suggests  *******************
>:
>:If you want to control the ability to mmap a low area of the address space, as configured by /proc/sys/kernel/mmap_min_addr.
>:Then you must tell SELinux about this by enabling the 'mmap_low_allowed' boolean.You can read 'mmap_selinux' man page for more details.

>:
>:*****  Plugin catchall (5.76 confidence) suggests  ***************************
>:
>:If you believe that wine-preloader should be allowed mmap_zero access on the  memprotect by default.
>:Then you should report this as a bug.
>:You can generate a local policy module to allow this access.
>:Do
>:allow this access for now by executing:
