Apple Issues New Warning to Millions of MacBook Users: Potential Battery Overheating Risk

Apple has confirmed the existence of a GPU vulnerability called LeftOverLocals that affects the M2 MacBook Air and potentially other Apple devices. The vulnerability allows attackers to read data left over from GPU processing, which can be exploited to listen in on another user's interactive session.

Qualcomm has released a firmware patch for the vulnerability and AMD is expected to release its own fix in March. Apple has already shipped fixes for the vulnerability within the latest M3 and A17 processors in the iPhone 17 Pro smartphones and new MacBook Pro laptops launching in the second half of 2023. However, it is unclear whether the vulnerability still exists in other Apple hardware, which could affect millions of users of iPhone, iPad, and Mac.

It is worth noting that anyone attempting to exploit this vulnerability must have physical access to the Mac, which means the risk of attack is lower than purely online attacks. Nonetheless, hackers could still use this attack as one stage of a multi-stage attack that could cause greater damage. Therefore, maintaining good physical security with Apple hardware is crucial in reducing the risk of attack.

Apple is expected to release a security update to resolve this issue quickly, and users are advised to update their software as soon as possible when it becomes available. The concern is that until a patch is released, activists, journalists, and other targeted individuals may be vulnerable to this security flaw.

Rachel Tobac, a security researcher at SocialProof Security, emphasizes the importance of upgrading to the latest software version and maintaining good physical security with Apple hardware. She advises users to be vigilant and cautious of any suspicious activity on their devices.

Overall, the LeftOverLocals vulnerability raises concerns about the security of Apple's hardware and software. It highlights the need for constant vigilance and timely software updates to protect against potential security vulnerabilities.
