**How does this impact SCOM customers?**

SCOM 2016, 2019, and 2022 customers who monitor Linux machines and use Kerberos-based authentication are impacted by this vulnerability.

**How can an attacker exploit the vulnerability?**

OMI supports Kerberos as one of the authentication mechanisms. This authentication mechanism is only used by SCOM, with no Azure service using it. A fixed temp file is used while keeping omi keytab in sync with the default keytab. The temp file can be manipulated by an attacker to insert a new key in the omi keytab and gain elevated privileges on the machine. The attacker must be locally logged in to the machine on which the OMI components are running.

**Does this vulnerability affect the Azure Services that use OMI?**

Other Azure services are not impacted by this vulnerability as they do not use Kerberos-based authentication. A Linux VM that is being monitored by SCOM, where SCOM has been configured to use Kerberos-based authentication is the only scenario which is impacted.
