Partial denial of service

Published Jul 21, 2026 · Updated Jul 21, 2026

Improper access control in the 2D component of Oracle Java SE and GraalVM releases allows remote attackers to cause partial denial of service. Oracle has not disclosed the specific 2D code path or the incorrect operation performed on untrusted input. Exploitation requires sandboxed Java Web Start or applet code from an untrusted source; server deployments loading only trusted administrator-installed code are not affected.
