A recently discovered vulnerability named LeftoverLocals has been confirmed to affect Apple’s M2 MacBook Air and potentially other devices. This vulnerability, which also impacts GPUs manufactured by Qualcomm, AMD, and Imagination, allows attackers to access residual data from GPU processing.
While the exploit has been demonstrated using an AI chatbot query, it is important to note that physical access to the targeted Apple device is required. This significantly reduces the risk compared to online attacks. Nevertheless, hackers might utilize this vulnerability as a part of a broader, multi-step attack.
Qualcomm has already released a firmware patch for its affected devices, urging users to promptly apply the update. AMD is currently developing its own fix, expected to be released in March.
Apple has taken steps to address the vulnerability by including fixes in its latest M3 and A17 processors, featured in the recently launched iPhone 17 Pro smartphones and new MacBook Pro laptops. However, it remains uncertain whether the vulnerability persists in other Apple hardware. Considering the extensive sales volume of iPhones, iPads, and Macs, potentially hundreds of millions of users could be affected.
Given the seriousness of the vulnerability, Apple is undoubtedly working diligently on a security update to swiftly resolve the issue. Users are advised to apply the update as soon as it becomes available to ensure their devices’ security.
It is crucial to maintain good physical security practices to mitigate against this attack since it requires physical access to the targeted Mac. Additionally, staying informed about the latest developments in Apple’s security updates and following trusted sources for news in the Mac, iPhone, and App Store ecosystem is essential for ensuring optimal device security.
