The debate over Russia’s emerging “Irtysh” processors has taken a new and potentially serious turn. The processors are being advertized as a component of Russia’s initiative to achieve technological autonomy; however, the architecture that underpins them is LoongArch, which was created by Loongson in China. A recently disclosed vulnerability in Loongson processors has prompted an uncomfortable question: will Russia inherit the vulnerabilities discovered in the Chinese processor architecture if it uses it for sensitive systems?
This matter is especially significant because the Irtysh project has already been scrutinized for the extent to which its proposed processors resemble existing Chinese Loongson products. Tramplin Electronics, a Russian company, has introduced the Irtysh C616 and C632 processors, which are built on licensed LoongArch technology. However, Russian government documents and industry reporting have raised questions about the technical identity of the chips and their relationship to Loongson processors. The technical identity of Irtysh processors and Chinese Loongson products was purportedly called into doubt by the Ministry of Industry and Trade of Russia in April 2026.
Irtysh’s Chinese Architecture
LoongArch is not simply a Russian processor architecture with a Chinese connection. It is an instruction-set architecture that was created by Loongson and is currently supported by the Linux kernel. It is a 64-bit RISC architecture that possesses its own instruction set and extensions, which include vector and cryptographic capabilities.
That distinction matters enormously for security.
The underlying CPU architecture is not automatically converted to a Russian one by altering the name of a processor package, incorporating Russian-developed modules, or establishing a distinct software environment. Architectural defects may potentially impact all implementations that retain the vulnerable behavior if the fundamental processor design inherits characteristics of LoongArch.
That concern has become much more concrete with the disclosure of LoongLeak.
What is LoongLeak?
In August 2026, LoongLeak was introduced by researchers from the CISPA Helmholtz Center for Information Security in Germany at the USENIX Security Symposium. Their research investigated LoongArch processors and identified an architectural information-leakage mechanism that can transcend privilege boundaries.
The researchers discovered that a LoongArch instruction has the potential to leave 32 bits of a register in an undefined or uncertain state. These bits may contain information that originates from the processor’s L1 data cache when specific conditions are met. Information from another application or the operating system may become visible because the cache is not isolated between applications.
The researchers did not simply demonstrate that information could theoretically leak. The practical implications of their experiments were evident. The researchers were able to bypass protections such as ASLR and stack canaries, recover full-disk AES keys from the kernel, and obtain portions of root password hashes from user space, as per the published research.
The attack can be conducted from unprivileged software, containers, and virtual machines, which is particularly significant for modern data centers. The researchers demonstrated that the leakage can cross a virtual-machine boundary, potentially allowing data belonging to a host system to be exposed from inside a guest VM.
Why This Matters for Russia
The discovery does not imply that all Loongson or LoongArch-based computers are automatically compromised, nor does it establish that China intentionally inserted a backdoor into the architecture. That distinction is important.
Vulnerabilities have existed in processors designed in the United States, Europe, China and elsewhere. Over the years, Intel, AMD, and other significant processor manufacturers have all encountered significant hardware security vulnerabilities.
The issue for Russia is different: technological sovereignty is being presented as a security objective.
If a processor intended for sensitive Russian infrastructure is reliant on a foreign instruction-set architecture, Russia is still reliant on the architectural decisions, documentation, design assumptions, and security updates of another country. Discoveries such as LoongLeak demonstrate why that dependency cannot simply be dismissed as a political or branding issue.
The Vulnerability Cannot Simply Be “Patched Away”
Researchers have classified the leakage as architectural, which is why LoongLeak is of particular concern. The underlying hardware behavior cannot be eliminated through conventional software patching. Mitigation may necessitate the prevention of sensitive information from remaining in the L1 cache or the disabling of one hardware thread per core on affected processors, thereby effectively renouncing simultaneous multithreading.
Nevertheless, there is a critical caveat. Loongson has already addressed the issue in an update for its 3A6000 processor, with the reported cache-eviction mitigation producing a relatively small performance impact of about 1.4 percent in worst-case testing.
This implies that the discovery does not serve as evidence that LoongArch is ineffective. It is evidence that foreign processor architectures must undergo an extremely rigorous security evaluation before being trusted with sensitive workloads.
Irtysh and the Sovereignty Question
This is the point at which the Irtysh controversy becomes more significant.
The Irtysh processors have been advocated for applications that include data centers and potentially critical information infrastructure. However, the company’s engineering samples are not scheduled to be released to the market until 2027, as indicated by its reported roadmap. Concurrently, Tramplin Electronics has acquired declarations regarding Chinese Loongson servers, which further complicates questions regarding the project’s technological dependence.
Therefore, the security debate should not be reduced to the question of whether the processor has Cyrillic markings or whether additional Russian-designed modules are incorporated around the CPU.
The fundamental question is significantly simpler: what precisely is Russian, and what is still reliant on Chinese technology?
If the CPU core and instruction-set architecture are not produced in Russia, it is impossible for Russia to assume that the presence of additional domestic components will automatically mitigate foreign architectural risks.
The Real Lesson From LoongLeak
The broader lesson is not that Chinese technology is uniquely dangerous. The same logic applies to American, European, or any other foreign technology.
The unavoidable reality of modern computing is illustrated by a vulnerability that was discovered in a foreign architecture: relying on the design decisions of another individual implies trusting the processor of another individual.
That may be a reasonable compromise for standard commercial computing. The standard must be significantly higher for systems that manage military information, strategic communications, nuclear infrastructure, intelligence data, or other critical national assets.
Therefore, Russia is confronted with a decision. It is able to continue utilizing foreign architectures because they provide a more expeditious path to commercially viable processors while simultaneously establishing a protective layer of certification and security. Alternatively, it may allocate resources to processor architectures and ecosystems that are truly autonomous, recognizing that this will necessitate years of engineering, substantial funding, and a protracted software development endeavor.
