RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

***** Plugin catchall (100. confidence) suggests **************************
If you believe that python2.7 should be allowed write access on the directory 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:
# grep yum /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Here is my reproducer, but it uses a different ABRT addon:
# sleep 120 &

# kill -6 2315
#
[1]+ Aborted (core dumped) sleep 120

Here are suggestions produced by audit2allow (enforcing mode):
allow sosreport_t NetworkManager_t:dbus send_msg;
allow sosreport_t NetworkManager_var_run_t:sock_file write;
allow sosreport_t self:netlink_audit_socket create;
allow sosreport_t semanage_store_t:dir write;
allow sosreport_t var_lib_nfs_t:dir write;
Gathered AVCs will be attached.
