New Rowhammer Technique

Rowhammer is an attack technique involving accessing -- thats "hammering" -- rows of bits in memory, millions of times per second, with the intent of causing bits in neighboring rows to flip. This is a side-channel attack, and the result can be all sorts of mayhem. Well, there is a new enhancemen...

New Blacksmith Exploit Bypasses Current Rowhammer Attack Defenses

Cybersecurity researchers have demonstrated yet another variation of the Rowhammer attack affecting all DRAM dynamic random-access memory chips that bypasses currently deployed mitigations, thereby effectively compromising the security of the devices. The new technique — dubbed "Blacksmith"...

CVE-2021-42114

A Rowhammer flaw was found in the latest DDR4 DRAM hardware chips. This flaw is different from the previously known attack CVE-2020-10255 by non-uniform patterns of memory access. These DDR4 DRAM hardware chips implement a Target Row Refresh TRR mitigation to prevent a Rowhammer flaw-induced bit...
