Description cirelli94+fedora 2023-12-31 11:20:44 UTC
Description of problem:
I'm playing the witcher 3 on Steam.
Steam installed as RPM from Fedora repositories.
SELinux is preventing wine-preloader from using the 'execheap' accesses on a process.

*****  Plugin allow_execheap (53.1 confidence) suggests   ********************

If you do not think wine-preloader should need to map heap memory that is both writable and executable.
Then you need to report a bug. This is a potentially dangerous access.
Do
contact your security administrator and report this issue.

*****  Plugin catchall_boolean (42.6 confidence) suggests   ******************

If you want to allow selinuxuser to execheap
Then you must tell SELinux about this by enabling the 'selinuxuser_execheap' boolean.

Do
setsebool -P selinuxuser_execheap 1

*****  Plugin catchall (5.76 confidence) suggests   **************************

If you believe that wine-preloader should be allowed execheap access on processes labeled unconfined_t 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:
# ausearch -c 'wine-preloader' --raw | audit2allow -M my-winepreloader
# semodule -X 300 -i my-winepreloader.pp
