Attack of the Killer Bugs

The vulnerability, tracked as CVE-2023-4211, affects multiple versions of the Midgard, Bifrost, Valhall, and Arm 5th Gen GPU Architecture Kernel Driver. Basically, a local non-privileged user can misuse GPU memory to gain access to already freed memory. Sounds like a bad case of tech-deja vu, doesn't it?

Google to the Rescue

Our saviors in this scenario are Maddie Stone from Google's Threat Analysis Group and Jann Horn from Google Project Zero. They found indications of targeted exploitation of this flaw, alongside another severe one affecting the Chrome web browser. We can't even fault them for having a cooler superhero origin story than most.

The Spy Who Hacked Me

While it remains unclear who's behind these attacks, it seems they might be part of a spyware campaign targeting high-risk individuals. So, if you've got any secrets worth spying for, better watch out for your Arm Mali GPU Kernel Driver.

Deja Vu All Over Again

This isn't the first time Arm Mali GPU Kernel Driver has been exploited. Earlier this year, a series of flaws were used by a spyware vendor to penetrate Samsung devices. If there's a hole, somebody's going to try and crawl through it. It's a bit like a tech version of Groundhog Day, with less Bill Murray and more cybersecurity alerts.
