CVE-2023-22025Network attack vector

Data modification via oversized masked vector load

Published Oct 17, 2023 · Updated Sep 13, 2024

Memory corruption in HotSpot in Oracle Java SE 8u381-perf, 17.0.8, and 21 allows remote attackers to modify accessible data. LoadVectorMaskedNode::Ideal fails to discard a masked vector load whose constant mask makes the load exceed MaxVectorSize, producing invalid code. Exploitation requires AVX-512 via UseAVX=3 and untrusted code reaching HotSpot, such as through a web service or sandboxed Java client.
