Synopsis
The remote Red Hat host is missing one or more security updates for java-25-openjdk.Description
The remote Redhat Enterprise Linux 10 / 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:9693 advisory.The OpenJDK 25 packages provide the OpenJDK 25 Java Runtime Environment and the OpenJDK 25 Java Software Development Kit.
Security Fix(es):
* JDK: Enhance crypto algorithm support (CVE-2026-22007)
* JDK: Improved Arena allocations (CVE-2026-22008)
* JDK: Improve Kerberos credentialing (CVE-2026-22013)
* JDK: Enhance Path Factories Redux (CVE-2026-22016)
* JDK: Enhance Zip file reading (CVE-2026-22018)
* JDK: Enhance certificate chain validation (CVE-2026-22021)
* JDK: Updating FreeType 2.14.1 (CVE-2026-23865)
* JDK: Enhance TLS connection handling (CVE-2026-34282)
* JDK: Enhance key generation (CVE-2026-34268)
This release also updates a number of third-party libraries included in the JDK. The libraries themselves are affected by the following CVEs, but this is not a statement that the JDK itself is affected:
* giflib: Denial of Service via buffer overflow in EGifGCBToExtension (CVE-2026-26740)
* libpng: Information disclosure and denial of service via out-of-bounds read/write in Neon palette expansion (CVE-2026-33636)
* libpng: Arbitrary code execution due to use-after-free vulnerability (CVE-2026-33416)
Bug Fix(es):
* When copying files, OpenJDK 25 prefers to use the copy_file_range native function for performance reasons, only falling back to sendfile when this fails. However, in previous OpenJDK 25 releases, a response of EOPNOTSUPP (operation not supported) did not cause the JDK to fall back to sendfile. This is rectified in this release. (RHEL-169939, RHEL-169937)
