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 haven’t been as common; according to a report by Ars Technica, there appears to be a flaw that directly targets GDDR memory. The attacks are labeled ‘Rowhammer,’ and the latest report suggests they have now been extended to NVIDIA’s Ampere GPUs, such as the RTX 3060 and RTX A6000. Potential attackers could get access to your systems in a pretty interesting way, which we’ll discuss ahead.
Rowhammer attacks have previously been limited to system memory, such as DDR modules, but the latest research indicates they have been extended to GPU memory as well, which is why they affect the broader gaming community. Now, gaining system-level access via simple DDR modules might seem odd at first, but as Rowhammer demonstrates, it can manipulate individual memory chips within the GPU through electrical interference. The GPU memory is tricked into believing that ‘sensitive’ data is in a secure location, but in reality, it has already been exposed.
