New Rowhammer Attack Can Grant Kernel-Level Control on Nvidia Workstation GPUs

New Rowhammer attack can grant kernel-level control on Nvidia workstation GPUs

A study from researchers at UNC Chapel Hill and Georgia Tech shows that GDDR6-based Rowhammer attacks can grant kernel-level access to Linux systems equipped with GPUs based on Nvidia's Ampere and Ada Lovelace architectures. The vulnerability appears significantly more severe than what was outlined in a paper last year.Read Entire Article

NVIDIA's GPUs Are Great At Gaming, But Even Better At Handing Hackers Your Entire System With New "Rowhammer" Attacks

NVIDIA's gaming GPUs have been hit by the 'Rowhammer' vulnerability, a security flaw that has existed for more than a decade and is troublesome for the average consumer. New Research Indicates that Rowhammer Attacks Can Now Target GDDR Memory, Which Is in All Gaming GPUs Vulnerabilities in hardware components aren't uncommon, and intruders have long meddled with your CPUs to compromise systems. However, in the case of GPUs, the vulnerabilities h…

New 'GeForge' and 'GDDRHammer' attacks can fully infiltrate your system through Nvidia's GPU memory — Rowhammer attacks in GPUs force bit flips in protected VRAM regions to gain read/write access

Two new Rowhammer attacks for GPUs have been discovered that can cause bit flips in VRAM to gain arbitrary read/write access over it. These attacks target page files and the page directory that are otherwise protected from electrical disturbance by the driver. By "massaging" these data structures into vulnerable regions where a bit flip can occur, the attacker can access even the CPU memory.

Users of NVIDIA Ampere-based GPUs equipped with GDDR6 memory beware—new Rowhammer attacks are in the wild that exploit these cards for a full system control hijack. It is not all Ampere GPUs affected, however. The only ones on which the vulnerability has been tested and proven are the NVIDIA GeForce RTX 3060 and RTX A6000.
