Description of problem:
When firefox crashed while using webcam on meeting, I got this selinux alert.

I don't think the gdb can find anything useful on video0 device so it might make sense to dontaudit or change the tracer to ignore devices?
SELinux is preventing gdb from 'read' accesses on the chr_file video0.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that gdb should be allowed read access on the video0 chr_file 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 'gdb' --raw | audit2allow -M my-gdb
# semodule -X 300 -i my-gdb.pp
