Summary
openjdk-25 vulnerabilities
Details

Thomas Beckers discovered that the JAXP component of OpenJDK 25 did not correctly authenticate certain APIs. A remote unauthenticated attacker could possibly use this issue to gain unauthorized access to sensitive information. (CVE-2026-22016)

It was discovered that the Networking component of OpenJDK 25 did not correctly authenticate certain APIs. A remote unauthenticated attacker could possibly use this issue to cause a denial of service. (CVE-2026-34282)

It was discovered that the JSSE component of OpenJDK 25 did not correctly authenticate certain APIs. A remote unauthenticated attacker could possibly use this issue to cause a denial of service. (CVE-2026-22021)

It was discovered that the JGSS component of OpenJDK 25 did not correctly authenticate certain APIs. A remote attacker could possibly use this issue to obtain sensitive information. (CVE-2026-22013)

It was discovered that the 2D component of OpenJDK 25 did not correctly handle certain integer arithmetic. If a user or automated system were tricked into opening a specially crafted file, an attacker could possibly use this issue to obtain sensitive information. (CVE-2026-23865)

It was discovered that the Libraries component of OpenJDK 25 did not correctly authenticate certain APIs. A remote unauthenticated attacker could possibly use this issue to modify data. (CVE-2026-22008)
