Out-of-bounds read in Eclipse OMR's arraycmp SIMD JIT implementation for IBM Z (s390x) and IBM POWER (P10) architectures - versions up to 0.11 - allows a low-privileged network-reachable attacker to trigger an application crash when a zero-length array comparison is JIT-compiled and executed. The flaw exists exclusively in the SIMD code-generation paths for these two architectures and has no impact on x86 or ARM deployments. No active exploitation has been confirmed (no CISA KEV listing) and no public exploit has been identified at time of analysis; exploitation is further constrained by high attack complexity and the requirement for user interaction.
