Description of problem:
It can be reproduced by running a simple container using podman compose in a rootless podman context.

```
services:
  app:
    image: hello-world
```

Using slirp4netns or none as `network_mode` rather than 'pasta' prevents this issue.
SELinux is preventing /usr/bin/nft from read, write access on the chr_file /dev/udmabuf.

*****  Plugin leaks (86.2 confidence) suggests   *****************************

If you want to ignore nft trying to read write access the udmabuf chr_file, because you believe it should not need this access.
Then you should report this as a bug.  
You can generate a local policy module to dontaudit this access.
Do
# ausearch -x /usr/bin/nft --raw | audit2allow -D -M my-nft
# semodule -X 300 -i my-nft.pp

*****  Plugin catchall (14.7 confidence) suggests   **************************

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