AWS AmazonRDS: Oracle minor version upgrades: MRPs, security patches, 19c support
Summary
Updates RDS for Oracle minor version upgrade documentation to extend MRP (Monthly Recommended Patch) format and behavior to Oracle Database 19c, clarifies that MRPs contain Critical Security Patch Updates, and notes that MRPs shipped with quarterly RUs are applied by automatic minor version upgrades while between-quarter MRPs must be applied manually.
Security assessment
The changed line documents that Oracle RDS minor versions include MRPs containing a Critical Security Patch Update, and the added paragraph explains that between-quarter MRPs are NOT applied automatically and must be applied manually. This is security guidance about timely security patching of database engines, but it describes a feature/behavior rather than addressing a specific vulnerability or incident, so it is not tied to a concrete CVE or security issue.
Evidence
+RDS for Oracle releases new minor engine versions of Oracle Database 19c (19.0.0.0) and Oracle Database 26ai (26.0.0.0) quarterly. Beginning with the July 2026 quarterly RU, each of these engine versions includes an RU component and an MRP component. An RU includes the patches that Oracle releases for the specified quarter. An MRP includes a Critical Security Patch Update and other fixes that Oracle recommends.
