Description of problem:
On each boot (ThinkPad L14)
SELinux is preventing pool-ModemManag from 'getattr' accesses on the chr_file /dev/wwan0mbim0.

*****  Plugin device (91.4 confidence) suggests   ****************************

If you want to allow pool-ModemManag to have getattr access on the wwan0mbim0 chr_file
Then you need to change the label on /dev/wwan0mbim0 to a type of a similar device.
Do
# semanage fcontext -a -t SIMILAR_TYPE '/dev/wwan0mbim0'
# restorecon -v '/dev/wwan0mbim0'

*****  Plugin catchall (9.59 confidence) suggests   **************************

If you believe that pool-ModemManag should be allowed getattr access on the wwan0mbim0 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 'pool-ModemManag' --raw | audit2allow -M my-poolModemManag
# semodule -X 300 -i my-poolModemManag.pp
