Samsung Launches 6GB RAM Chips for Next Generation Smartphones

With Launch of Galaxy S6 and Galaxy S6 Edge, Samsung was the first one to bring 4GB RAM access in the Android mobile phones; with Samsung Note 5 and the current OnePlus 2 carrying the same RAM capacity. Now, today Samsung has again taken the technology a step further with the launch of 12GB LPDDR...

DRAM chip kernel mention the right vulnerability analysis-vulnerability warning-the black bar safety net

Security researchers found in the Intel PC on Linux systems you can use certain types of DDR DRAM chips in the presence of physical defects to obtain the highest system privileges. This technique is known as“Rowhammer”, which may make the recent generation of DRAM chips times the memory access...

Rowhammer Hardware Exploit Poses Threat DRAM Memory in Many Laptops, PCs

Software, from web apps, to operating systems to firmware, has been abused and exploited every which way from Sunday for decades by both researchers and attackers. Now, it is hardware’s turn in the spotlight, as researchers have published details of a new method for exploiting a problem with some...

DRAM Rowhammer vulnerability Leads to Kernel Privilege Escalation

Security researchers have find out ways to hijack the Intel-compatible PCs running Linux by exploiting the physical weaknesses in certain varieties of DDR DRAM double data rate dynamic random-access memory chips and gaining higher kernel privileges on the system. The technique, dubbed "rowhammer"...
