SAP Security Patch Day October 2026: what applies to your RISE system
20 new notes, four of them critical, with S/4HANA note 3798788 (CVSS 9.9) as this month's priority. Includes the open item from September: OVERPASS, the CVSS 10.0 kernel memory corruption flaw.
Upcoming dates
- Tuesday, November 10, 2026. The edition follows in the days after.
- Tuesday, December 8, 2026. Last Patch Day of the year.
Dates come from the calendar SAP publishes on its SAP Security Notes page. SAP has not yet published the 2027 calendar.
How to read each edition
Severity. SAP rates every note with a CVSS score and a priority: critical, high, medium or low. SAP treats notes with a CVSS of 7.0 or more as high priority.
Who handles it. On RISE with SAP, SAP ECS takes care of the technical layer: operating system, HANA database, kernel and Web Dispatcher. Fixes in ABAP code, such as those for S4CORE, SAP_BASIS or SAP_UI, are implemented on the customer side through SNOTE or a Support Package update. Each edition marks which is which.
What stays out. The bulletin includes products that are not part of a typical S/4HANA landscape, such as Commerce Cloud or development libraries. We list them separately so they do not get mixed up with what is urgent.
If you want someone to check every month which notes apply to your landscape and coordinate with SAP ECS, let's talk.
