Arbitrary Code Execution via Unvalidated JIT Instruction Generation

The vulnerability arises from improper input validation in the JIT compilation engine exposed via CFFI, enabling attackers to inject malicious code. This can lead to Arbitrary Code Execution at the host's privilege level.

Proof-of-concept demonstrates potential for severe exploitation, affecting diverse environments and emphasizing the need for immediate patching or mitigation.
