For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.
Note that the OpenJDK RPMs use the system certificate store, so the eMudhra CVEs (CVE-2026-91403 & CVE-2026-114820) should be resolved by updating the ca-certificates package.
