CVE-2026-70906· NVD / CVE Program· CNA oracle

Vulnerability in Oracle Java SE (component: 2D).

Noroxi assessment

Priority: Monitor (action score 30/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.46% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • Fixed version: java-25-openjdk (AlmaLinux:10) 1:25.0.4.1.1-1.1.el10.alma.1; java-25-openjdk-crypto-adapter (AlmaLinux:10) 1:25.0.4.1.1-1.1.el10.alma.1; java-25-openjdk-crypto-adapter-fastdebug (AlmaLinux:10) 1:25.0.4.1.1-1.1.el10.alma.1.

Low priority for now. Upgrade to java-25-openjdk (AlmaLinux:10) 1:25.0.4.1.1-1.1.el10.alma.1; java-25-openjdk-crypto-adapter (AlmaLinux:10) 1:25.0.4.1.1-1.1.el10.alma.1; java-25-openjdk-crypto-adapter-fastdebug (AlmaLinux:10) 1:25.0.4.1.1-1.1.el10.alma.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Vulnerability in Oracle Java SE (component: 2D). Supported versions that are affected are Oracle Java SE: 25.0.4 and 26.0.2. Easily exploitable vulnerability allows unauthenticated attacker with network access via multiple protocols to compromise Oracle Java SE. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Oracle Java SE. Note: This vulnerability can be exploited by using APIs in the specified Component, e.g., through a web service which supplies data to the APIs. This vulnerability also applies to Java deployments, typically in clients running sandboxed Java Web Start applications or sandboxed Java applets, that load and run untrusted code (e.g., code that comes from the internet) and rely on the Java sandbox for security. CVSS 3.1 Base Score 7.5 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
