CVE-2026-70906Network attack vector

Remote denial of service via 2D APIs

Published Aug 18, 2026 · Updated Aug 18, 2026

Denial of service in the 2D component of Oracle Java SE 25.0.4 and 26.0.2 allows remote attackers to hang or repeatedly crash the runtime. Oracle has not disclosed which 2D API or input triggers uncontrolled resource consumption. Exposure requires untrusted data to reach 2D APIs through a service or sandboxed Java Web Start or applet code; successful exploitation interrupts the affected runtime.
