Description of problem:
I started vscode on Fedora, that is all.
SELinux is preventing code from using the 'execheap' accesses on a process.
***** Plugin allow_execheap (53.1 confidence) suggests ********************
If you do not think code 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 code 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 'code' --raw | audit2allow -M my-code
# semodule -X 300 -i my-code.pp

I have the same issue, and it happens permanently, so often that I need to stop code, and sealert needs a few minutes until it calms down. I have here that the alert happened 1199 times in the few minutes I kept vscode open.Interestingly enough, the 2nd time where I start code during a desktop session, the issue doesn't happen. This is definitely a regression since upgrade to F40, and I have had the same execheap warning with other programs (but I didn't keep track, it wasn't a storm like with VSCode). Searching for execheap, I see other similar issues with chrome and wine-preloader (and I have in mind that Chromium was one of the impacted programs, but I can't reproduce currently).
BTW, I think that https://bugzilla.redhat.com/show_bug.cgi?id=2294469 is a duplicate.
