Impacted is confidentiality, integrity, and availability. The summary by CVE is:

In Splunk Enterprise versions below 10.4.3, 10.2.7, 10.0.10, and 9.4.15 on Linux, a local user who can run commands as the user account running Splunk Enterprise could cause an affected Linux package upgrade to run attacker-controlled operating-system commands with root privileges. The vulnerability is possible because the Linux package maintainer script trusts existing Splunk Enterprise installation content when it performs upgrade operations with root privileges. The vulnerability requires an affected Linux package upgrade to occur after the local user modifies the installation. The local user should not be able to elevate privileges at will.
