K60570139: Rowhammer hardware vulnerability CVE-2020-10255

Security Advisory Description Modern DRAM chips DDR4 and LPDDR4 after 2015 are affected by a vulnerability in deployment of internal mitigations against RowHammer attacks known as Target Row Refresh TRR, aka the TRRespass issue. To exploit this vulnerability, the attacker needs to create certain...

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...

CVE-2021-42114

Modern DRAM devices PC-DDR4, LPDDR4X are affected by a vulnerability in their internal Target Row Refresh TRR mitigation against Rowhammer attacks. Novel non-uniform Rowhammer access patterns, consisting of aggressors with different frequencies, phases, and amplitudes allow triggering bit flips o...
