Kernel-level anti-cheat software has sparked a lot of debate, and it’s not hard to see why. On paper, it sounds like the perfect solution to those hackers ruining your perfectly good gaming experience. The reality? A bit more complicated, especially when you throw Linux systems and devices like the Steam Deck into the mix.
So, let’s dive in and take a look at the issues surrounding kernel-level anti-cheat—what it means, the risks involved, and why it’s a particularly thorny issue for certain operating systems.
What is Kernel-Level Anti-Cheat?
Kernel-level anti cheat essentially means anti-cheat software that operates at the deepest layer of your system, the kernel. The kernel isn’t just any part of your computer—it’s the like the software HQ area of your system that manages everything from hardware communication to memory and task scheduling. It’s the brain that ensures your operating system and other software runs smoothly.
For game developers, it’s the holy grail of cheat detection because, well, if you’ve got access to the kernel, there’s very little a cheater can hide from you. Cheaters like to mess with game code, inject scripts, or modify how a system handles a game to gain unfair advantages.
Kernel level anti-cheat software catches them right at the source, way down in the system’s guts where traditional anti-cheat software might miss them. But, and it’s a big ‘but’, messing around in this layer of the system comes with significant risks.
Privacy, Security, and Control Concerns
When an anti-cheat digs its claws into your kernel, it’s like handing someone the keys to your entire house. Sure, they might be a mate, but do you really know what they’re doing in there, rummaging through your digital drawers?
Security Risks: Kernel-level access means that if there’s even the tiniest crack in the anti-cheat software, some bad actor could sneak in and take over your whole system. We’re not just talking about your game anymore—your personal data is on the line. Malware could stroll right in, or worse, your computer could be taken over by someone with shady intentions. Picture your antivirus with a massive hole in it. Instead of being safe, you’re left wide open. That’s the risk here.
Privacy Concerns: Another massive issue is the privacy question. With kernel access, the anti-cheat software can technically access anything on your system. Everything. Your documents, browsing history, other software you’re running—it’s all fair game. Now, most anti-cheat providers will tell you they’re not snooping around, but the very fact they could raises all sorts of red flags.
Stability Risks: Kernel-level software, especially if not implemented well, can conflict with your system and cause crashes, or worse, system-wide errors like blue screens of death (BSOD). We’ve seen incidents where anti-cheat systems bricked systems because of bugs in the kernel-level code. When your system’s core functions are at risk, it’s not something to take lightly.
Why It’s a Headache for Linux and Steam Deck Users
Now, for Linux users and those gaming on Steam Deck (which runs on a Linux-based system), kernel-level anti-cheat introduces even more headaches. A lot of kernel-level anti-cheat software was designed with Windows in mind, and Linux has always been a second-class citizen in gaming land (though that’s changing thanks to Valve’s efforts). Here are the main issues:
The Issues for Steam Deck and Linux Users
- Compatibility Nightmares: Many kernel-level anti-cheat systems simply don’t play nice with Linux. This is a major issue when you’ve got a growing number of gamers using Linux-based systems like Steam Deck, where compatibility is already an ongoing battle. Alternative options for anti-cheat software such as Easy Anti-Cheat and BattlEye have started working with Linux, but it’s not quite there just yet. Not every game works, and even when it does, it’s often an unpredictable experience.
- Open-Source Ideology Conflict: The Linux community is big on open-source software. They value transparency—knowing exactly what’s happening in their systems. Kernel-level anti-cheat, on the other hand, is the antithesis of this. It’s proprietary software, often shrouded in secrecy for obvious reasons (they don’t want the cheaters to know how it works, after all). For Linux enthusiasts, giving a closed-source program access to the kernel feels like betrayal.
- Steam Deck’s Big Headache: The Steam Deck, which everyone’s been calling the handheld hero for PC gamers, has hit a bit of a snag with kernel level anti-cheat. Valve’s been pushing Proton (their clever tool for running Windows games on Linux) to make it all work, but let’s be real—it’s far from smooth sailing. Some games just won’t budge, refusing to launch or running like a car with a flat tyre because the anti-cheat software throws a tantrum.
When you’re trying to position a Linux-based handheld gaming device as a major competitor to the Nintendo Switch or Xbox, the last thing you want is for gamers to be locked out of their favourite online multiplayer titles because of anti-cheat hurdles.
Alternatives: Can We Do Better?
So, what’s the solution? Is there a way to have effective anti-cheat without the nuclear option of kernel-level access? Some developers have explored user-mode anti-cheat, which operates at a higher level of the system and doesn’t require deep kernel access. While less effective in catching more advanced cheats, it still tackles a majority of cheats without posing as much risk to the system’s integrity and privacy.
Additionally, developers could lean more into server-side anti-cheat solutions, where cheat detection happens on the game servers instead of the player’s device. Though this comes with its own limitations, it’s a safer approach for users.
Another solution is using services such as GeForce Now with devices like the Steam Deck which removes the problem completely as you are streaming from one of NVIDIA’s computers. Valve has also been working on anti-cheat compatibility layers specifically for Linux and Steam Deck, but this approach feels more like a patch than a real solution to the underlying problem.
Wrapping Up: Is Kernel-Level Anti-Cheat Worth It?
So, in a nutshell, kernel-level anti cheat might be great at stopping cheaters, but it’s far from perfect. It opens up some serious risks when it comes to your security, privacy, and system stability—especially if you’re rocking Linux or a Steam Deck. Until someone comes up with a better fix, or these issues get sorted, gamers are stuck in a bit of a bind: do you risk your system just to keep the cheaters out?
At the moment, it’s a classic catch-22—either you roll the dice with security or put up with the cheaters. Neither one’s a great option, really.
