CVE-2023-32184
📋 TL;DR
This vulnerability allows local attackers to execute arbitrary code as the user running opensuse-welcome by exploiting insecure storage of sensitive information when a custom layout is chosen. It affects openSUSE users who have opensuse-welcome installed and use custom layouts. The vulnerability enables privilege escalation from a local user account to the privileges of the opensuse-welcome process.
