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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL java-25-openjdk package based on the guidance in RHSA-2026:88347.
