By Bill Toulas, Bleeping Computer Security researchers have discovered five vulnerabilities in network equipment from Aruba (owned by HP) and Avaya (owned by ExtremeNetworks), that could allow malicious actors to execute code remotely on the devices. The damage caused by a successful attack ranges from data breach and complete device takeover to lateral movement and overriding network segmentation defenses. Security researchers from Armis cybersecurity company specialized on connected devices dubbed the vulnerability set “TLStorm 2.0” as the discovery is in the same class of issues as the of misuse of the NanoSSL TLS library, which they reported on popular APC UPS models. The analysts found that devices from other vendors have identical security risks and provided a list of affected products: Avaya ERS3500 Avaya ERS3600 Avaya ERS4900 Avaya ERS5900 Aruba 5400R Series Aruba 3810 Series Aruba 2920 Series Aruba 2930F Series Aruba 2930M Series Aruba 2530 Series Aruba 2540 Series

By Jack Dunhill, IFL Science One-way superconductivity without using magnetic fields has been discovered by researchers, smashing a strong barrier that held superconductivity from revolutionizing the electronics industry. While this feat was previously thought impossible, the researchers used 2D quantum materials to allow electricity to flow only one way through a superconducting material without any energy loss, enabling electronics to become magnitudes faster than what is currently possible with semi-conductors.  Their research was published in the journal Nature .  “If the 20th century was the century of semi-conductors, the 21st can become the century of the superconductor,” said professor Mazhar Ali, first author of the paper, in a statement .  Superconductivity is a goal like no other in electronics. When a material goes below a “critical” temperature (around -269°C), they become superconductors, in which electricity can pass through them with no resistance. Th...

Dell sets the record straight about its new CAMM design By Gordon Ung,  PCWorld If you were triggered over word that Dell is pushing a proprietary memory standard, take a chill pill. Dell’s new memory design isn’t really proprietary and may actually lead to benefits for performance laptops. The controversy kicked up last week when images of Dell’s new CAMM , or Compression Attached Memory Module, leaked out. This immediately lead tech sites to declare that Dell was taking a path to “ lock out user upgrades ” and warning laptop users who like to upgrade their memory that they were “ out of luck .” In an interview with PCWorld, however, both the person who designed and patented the CAMM standard, as well as the product manager of the first Dell Precision laptop to feature it, assured us the intent of the new memory module standard is to head-off looming bandwidth ceilings in the current SO-DIMM designs. Dell’s CAMM, in fact, could increase performance, improve reliability, aid user u...

DDR5 pricing concerns come to fore By Paul Alcorn, Tom's Hardware All signs indicate that AMD's next-gen AM5 socket platforms that will house the 5nm Ryzen 7000 'Raphael' processors will only support DDR5 memory when they arrive later this year, but it isn't official. However, we have now confirmed through multiple sources in the supply chain that the X670 and B650 AM5 platforms support only DDR5 memory, which has pricing implications for platforms built around AMD's upcoming Zen 4 processors. Additionally, we've also confirmed that AMD has moved to a chiplet-based design for the chipsets for its AM5 motherboards, so some models will come with two chipset dies. Given the long-lived eye-watering pricing we've seen for DDR5 memory, AMD's choice to only support DDR5 could prove to be a disadvantage in the face of Intel's Raptor Lake, which we have confirmed will continue to support both affordable DDR4 and expensive DDR5 memory, enabling two pricing...
