CVE-2026-30960
CriticalSummary
rssn is a scientific computing library for Rust, combining a high-performance symbolic computation engine with numerical methods and physics simulations. The vulnerability exists in the JIT compilation engine, fully exposed via CFFI. Due to improper input validation and external control of code generation, an attacker can supply malicious parameters or instruction sequences through the CFFI layer. Since the library often operates with elevated privileges, this allows arbitrary code execution at the privilege level of the host process.
Risk Assessment
The risk involves potential remote arbitrary code execution in the context of the process using the library, which could lead to full system compromise or data breach in computing environments.
Recommendation
It is recommended to update the rssn library to a patched version and to restrict access to the CFFI layer to trusted sources only.
Original NVD description (English source)
rssn is a scientific computing library for Rust, combining a high-performance symbolic computation engine with numerical methods support and physics simulations functionalities. The vulnerability exists in the JIT (Just-In-Time) compilation engine, which is fully exposed via the CFFI (Foreign Function Interface). Due to Improper Input Validation and External Control of Code Generation, an attacker can supply malicious parameters or instruction sequences through the CFFI layer. Since the library often operates with elevated privileges or within high-performance computing contexts, this allows for Arbitrary Code Execution (ACE) at the privilege level of the host process.
