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...
DRAM 'Rowhammer' Memory Bit Flip Privilege Elevation Vulnerability
DRAM, or Dynamic Random Access Memory, is the most common type of system memory. DRAM devices have security vulnerabilities that allow a local user to run a program that continuously accesses the DRAM, flipping the value of a cell from 1 to 0, or vice versa, allowing elevated privileges to execut...
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"...
