openjdk-8 vulnerabilities

Published Nov 29, 2023 · Updated Jun 25, 2026

Summary

It was discovered that the HotSpot VM implementation in OpenJDK did not
properly validate bytecode blocks in certain situations. An attacker could
possibly use this to cause a denial of service. (CVE-2022-40433)

Carter Kozak discovered that OpenJDK, when compiling with AVX-512
instruction support enabled, could produce code that resulted in memory
corruption in certain situations. An attacker targeting applications built
in this way could possibly use this to cause a denial of service or execute
arbitrary code. In Ubuntu, OpenJDK defaults to not using AVX-512
instructions. (CVE-2023-22025)

It was discovered that the CORBA implementation in OpenJDK did not properly
perform deserialization of IOR string objects. An attacker could possibly
use this to bypass Java sandbox restrictions. (CVE-2023-22067)

It was discovered that OpenJDK did not properly perform PKIX certification
path validation in certain situations. An attacker could use this to cause
a denial of service. (CVE-2023-22081)
