New GPUBreach attack enables system takeover via GPU rowhammer
A new attack, dubbed GPUBreach, can induce Rowhammer bit-flips on GPU GDDR6 memories to escalate privileges and lead to a full system compromise. GPUBreach was developed by a team of researchers at the University of Toronto, and full details will be presented at the upcoming IEEE Symposium on Security & Privacy on April 13 in […]
New Phoenix attack bypasses Rowhammer defenses in DDR5 memory
Academic researchers have devised a new variant of Rowhammer attacks that bypass the latest protection mechanisms on DDR5 memory chips from SK Hynix. A Rowhammer attack works by repeatedly accessing specific rows of memory cells at high-speed read/write operations to cause enough electrical interference to alter the value of the nearby bits from one to […]
NVIDIA shares guidance to defend GDDR6 GPUs against Rowhammer attacks
NVIDIA is warning users to activate System Level Error-Correcting Code mitigation to protect against Rowhammer attacks on graphical processors with GDDR6 memory. The company is reinforcing the recommendation as new research published by the University of Toronto demonstrates the practicallity of Rowhammer attacks against an NVIDIA A6000 GPU (graphical processing unit). “We ran GPUHammer on an NVIDIA RTX A6000 […]
Claude catches up to ChatGPT with built-in memory support
AI startup Anthorpic is planning to add a memory feature to Claude in a bid to take on ChatGPT, which has an advanced memory feature. With memory support, Claude can remember past events and reference them in new chats to improve the results. For example, if you specifically instruct Claude that you prefer Python as your […]
ChatGPT rolls out Memory upgrade for free users
ChatGPT’s memory feature is now better and capable of referencing past conversations for free accounts. In an update to its support document, OpenAI quietly confirmed that it has rolled out a new version of Memory that better remembers and references your past conversations. This feature was previously available for paid subscribers, but it’s rolling out to […]
OpenAI wants ChatGPT to know you over your life with new Memory update
OpenAI is upgrading ChatGPT’s memory feature with the ability to remember and reference all the past conversations. The Memory feature isn’t new and has been around for more than a year. With Memory, ChatGPT can save conversations, especially when you ask the AI to remember something. For example, if you ask ChatGPT to remember that you don’t […]
Microsoft fixes Windows Server 2022 bug breaking device boot
Microsoft has fixed a bug that was causing some Windows Server 2022 systems with two or more NUMA nodes to fail to start up. NUMA (short for non-uniform memory access) is a computer memory architecture in which multiple processors are connected to the same shared memory pool via high-speed interconnections to control performance bottlenecks. This design […]
Microsoft shares temp fix for Outlook crashing when writing emails
Microsoft has shared a temporary fix for a known issue that causes classic Outlook to crash when writing, replying to, or forwarding an email. These problems appear after updating Outlook for Microsoft 365, Outlook 2021, Outlook 2019, or Outlook 2016 to Version 2412 (Build 18324.20168), released on January 7, and will trigger “0xc0000005” exception codes. “You […]
Google sees 68% drop in Android memory safety flaws over 5 years
The percentage of Android vulnerabilities caused by memory safety issues has dropped from 76% in 2019 to only 24% in 2024, representing a massive decrease of over 68% in five years. This is well below the 70% previously found in Chromium, making Android an excellent example of how a large project can gradually and methodically move to […]
