Quarterly Security Patch Updates

Security Updates are collections of security fixes for supported versions of Splunk products. We plan to create Security Patch Updates and make them available through scheduled cloud releases or on-premises maintenance releases for supported versions of Splunk products at the time of the quarterly advisory disclosure. When patches can not be backported due to technical feasibility or otherwise, we will publish mitigation and additional compensating control guidance.

Security Patch Updates are published quarterly in February, June, August and November. Customers are encouraged to sign up for our RSS feed to receive a notification when advisories have been published.
