Huawei proposes to launch a new sandbox mode for the Linux kernel
Reportedly, the Linux kernel has already tried Rust programming to improve memory security. Now, the Chinese tech giant Huawei is planning a proposal for a new “sandbox mode” for the Linux kernel to improve the C language code in the kernel. memory safety.
Linux emails show that Petr Tesarik of Huawei Cloud issued a “request for comments” patch series about the new sandbox mode. Petr described the sandbox mode as:
The ultimate goal of sandbox mode is to execute native kernel code in an environment that only allows memory access to predefined addresses, so potential vulnerabilities cannot be exploited or have no impact on the rest of the kernel.
This patch series adds sandbox-mode APIs and architecture-independent infrastructure to the kernel. It runs the target function on a vmalloc() copy of all input and output data. This alone prevents some out-of-bounds access due to the protected page.
The sandbox mode document description,
The main goal of Sandbox Mode (SBM) is to reduce the impact of potential memory safety bugs in the kernel code by breaking up the kernel. The SBM API allows each component to be run in an isolated execution environment. In particular, memory regions used as inputs and/or outputs are isolated from the rest of the kernel and surrounded by guard pages.
On an architecture that implements the necessary arch hooks, sandbox mode leverages hardware paging facilities and CPU privilege levels to force the use of only these predefined memory regions. With support from Arch, SBM can also recover from protection breaches. This means that SBM forcibly terminates the sandbox and returns an error code (such as “-EFAULT“) to the caller so that execution can continue. This implementation provides *strong isolation*.
The FutureNet World 2025 event just completed in London, bringing together over 700 industry leaders to talk about the future of network technology. The yearly gathering attracts top executives from global telecom companies, standards organizations, and technology suppliers. For the first time ever, the event created a special “Intelligent Network Best Practice Award” – and Huawei won the prize.
The company stands for its innovative work on smart, self-managing networks. Huawei’s winning technology helps telecom companies run their networks more intelligently with less human intervention. Their solution includes smart digital assistants designed for network maintenance, improving customer experience, and business operations.
These digital helpers fall into two main categories – the Mate series and the Spirit series. The technology has already been rolled out in many countries, showing impressive results across different types of networks including IP, optical, wireless, and core systems. Speaking at the event, Wang Shaosen, who leads Huawei’s smart network solutions, shared the company’s vision: “We’re committed to developing technology that makes networks smarter.
This will help telecom companies succeed with advanced 5G services and prepare for the future of 6G connectivity.
