New Spectre-V2 security exploit targets Intel Alder Lake CPUs
Intel’s Alder Lake processors are among the best gaming CPUs on the market, but a newly discovered security exploit could leave gaming PCs powered by 12th Gen Core chips vulnerable to attack. Unfortunately, a new mode of Spectre-V2 attack has come to haunt the company’s latest LGA 1700 silicon.
The exploit relies on ‘branch injection history’ (BHI) and was discovered by the Systems and Network Security Group at Vrije Universiteit Amsterdam (VUSec). Essentially, BHI allows a potential attacker to trick the CPU’s kernel into leaking sensitive data by abusing branch prediction, something that practically all processors use to speed up processes. If conducted successfully, sensitive data that would otherwise be hidden is revealed, such as passwords.
What makes Spectre-V2 attacks more dangerous than most other cyberattacks is that it targets a PC’s hardware directly, allowing it to be potentially applied across multiple operating systems, including Windows 10 and 11. According to WCCFTech, Intel plans to address the exploit with a patch, but the company didn’t provide any timeframe for when the fix will arrive.
