NVIDIA and Arm have urged clients to improve their merchandise after revealing a collection of recent vulnerabilities.
Arm introduced an actively exploited zero-day vulnerability in its Mali GPU Kernel Driver which permits “improper GPU reminiscence processing operations.”
Listed as CVE-2024-4610, the vulnerability impacts all variations of its Bifrost and Valhall drivers, from r34p0 to r40p0.
“An area non-privileged consumer could make improper GPU reminiscence processing operations to realize entry to already freed reminiscence,” the advisory famous. “Arm is conscious of studies of this vulnerability being exploited within the wild. Customers are really useful to improve if they’re impacted by this challenge.”

In the meantime, a brand new NVIDIA safety bulletin for June revealed 10 new excessive and medium-severity vulnerabilities in its GPU Show Driver and VGPU software program merchandise.
Safety specialists highlighted CVE‑2024‑0090 as probably essentially the most severe. The out-of-bounds write bug may result in code execution, denial of service, escalation of privileges, data disclosure and information tampering, NVIDIA mentioned.
“CVE‑2024‑0090 is regarding given its versatility to an attacker, the truth that it impacts each Home windows and Linux, and the ubiquity of Nvidia GPUs within the general assault floor,” argued Bugcrowd founder, Casey Ellis. “I wouldn’t be stunned to see it included in assault tooling within the not-too-distant future.”
John Bambenek, president of Bambenek Consulting, additionally urged warning.
“Judging from the CVSS scores, it doesn’t appear that NVIDIA believes distant execution of those vulnerabilities is feasible,” he argued.
“The priority right here is that generally machine drivers could be neglected as a part of the patching course of, particularly when not a part of the OS patch course of. Due to this fact, particular effort could also be wanted to seek out these susceptible techniques and patch them, which is able to possible require a reboot.”
