Nethammer—Exploiting DRAM Rowhammer Bug Through Network Requests

Last week, we reported about the first network-based remote Rowhammer attack, dubbed Throwhammer, which involves the exploitation a known vulnerability in DRAM through network cards using remote direct memory access RDMA channels. However, a separate team of security researchers has now...

CVE-2017-17046

Xen vulnerability CVE-2017-17046 affects Xen up to 4.9.x on ARM, where a guest OS user can read sensitive DRAM data after reboot due to mishandling of disjoint blocks and non-zero-start physical addresses. Impact is information disclosure within the guest context; local attacker privileges requir...

How to use Rowhammer vulnerability Root Android phone with Video demo+Exploit source code-the vulnerabilities and early warning-the black bar safety net

! Recently, security research experts through research found a root the Android phone to the new method, i.e., by Rowhammer vulnerability to root Android phone. In addition, the attacker can even use this exploit with presently known Android vulnerabilities Bandroid and Stagefright to the target...

New Drammer Android Hack lets Apps take Full control (root) of your Phone

Earlier last year, security researchers from Google's Project Zero outlined a way to hijack the computers running Linux by abusing a design flaw in the memory and gaining higher kernel privileges on the system. Now, the same previously found designing weakness has been exploited to gain unfettere...

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"...
