Sinkclose is a security vulnerability in certain AMD microprocessors dating back to 2006 that was made public by IOActive security researchers on August 9, 2024. [1] IOActive researchers Enrique Nissim and Krzysztof Okupski presented their findings at the 2024 DEF CON security conference in Las Vegas [2] in a talk titled "AMD Sinkclose: Universal Ring-2 Privilege Escalation".
The ZEN MicroPhoto, released on July 28, 2005, [15] shares the same features of the ZEN Micro except Audible.com support (reinstated in firmware versions 1.31.01 and above), and adds an upgraded 262,144-color (18 bpp) OLED screen for displaying photos. To fix the lack of bass with the ZEN Micro, Creative implemented a Bass Boost feature ...
The ZEN MX's button layout is slightly altered, merging the play/pause button with the power button. The ZEN MX extends importing from SD card to internal memory and library beyond the ZEN's picture import mode, adding music. [16] The ZEN MX features the MSC/UMS transfer system that makes the player compatible with Apple computers. The ZEN MX ...
The DAO bug. On June 17, 2016, the DAO was subjected to an attack exploiting a combination of vulnerabilities, including the one concerning recursive calls, that resulted in the transfer of 3.6 million Ether – around a third of the 11.5 million Ether that had been committed to The DAO – valued at the time at around $50M.
Zen+ is the name for a computer processor microarchitecture by AMD.It is the successor to the first gen Zen microarchitecture, [3] and was first released in April 2018, [4] powering the second generation of Ryzen processors, known as Ryzen 2000 for mainstream desktop systems, Threadripper 2000 for high-end desktop setups and Ryzen 3000G (instead of 2000G) for accelerated processing units (APUs).
Former Rep. Matt Gaetz fired back at “Reacher” star Alan Ritchson, who claimed they were “adversaries” when they attended the same Florida high school. “Hollywood apparently changes ...
Furthermore, Zen 4 Cloud (a variant of Zen 4), abbreviated to Zen 4c, was also announced. Zen 4c is designed to have significantly greater density than standard Zen 4 while delivering greater power efficiency. This is achieved by redesigning Zen 4's core and cache to maximise density and compute throughput.
Retbleed is a speculative execution attack on x86-64 and ARM processors, including some recent Intel and AMD chips. [1] [2] First made public in 2022, it is a variant of the Spectre vulnerability which exploits retpoline, which was a mitigation for speculative execution attacks.
