CVE-2022-42961
An issue was discovered in wolfSSL before 5.5.0. A fault injection attack on RAM via Rowhammer leads to ECDSA key disclosure. Users performing signing operations with private ECC keys, such as in server-side TLS connections, might leak faulty ECC signatures. These signatures can be processed via ...

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...
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...
Privilege escalation
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...
CVE-2021-42114
CVE-2021-42114 (Blacksmith) affects modern DRAM (PC‑DDR4, LPDDR4X) where TRR mitigations can be bypassed by non‑uniform memory access patterns. ETH Zurich et al. demonstrated a fuzzer (Blacksmith) that triggered bit flips across 40 DRAM devices from major vendors (Samsung, SK Hynix, Micron), enab...
CVE-2021-42114 Scalable Rowhammering In the Frequency Domain to Bypass TRR Mitigations On Modern DDR4/LPDDR4X Devices
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...

DDR4 DRAM security vulnerabilities
Ddr4 Dram is a synchronous dynamic random access memory. A security vulnerability exists in DDR4 DRAM that originated in the product that allows an unprivileged system user to use a Rowhammer attack variant to trigger bit corruption across memory spaces. An attacker could cause a denial of servic...
As Chips Shrink, Rowhammer Attacks Get Harder to Stop
A full fix for the “Half-Double” technique will require rethinking how memory semiconductors are designed...
Google Researchers Discover A New Variant of Rowhammer Attack
A team of security researchers from Google has demonstrated yet another variant of the Rowhammer vulnerability that targets increasingly smaller DRAM chips to bypass all current mitigations, making it a persistent threat to chip security. Dubbed "Half-Double," the new hammering technique hinges o...
New JavaScript Exploit Can Now Carry Out DDR4 Rowhammer Attacks
Academics from Vrije University in Amsterdam and ETH Zurich have published a new research paper describing yet another variation of the Rowhammer attack. Dubbed SMASH Synchronized MAny-Sided Hammering, the technique can be used to successfully trigger the attack from JavaScript on modern DDR4 RAM...
New Browser Attack Allows Tracking Users Online With JavaScript Disabled
Researchers have discovered a new side-channel that they say can be reliably exploited to leak information from web browsers that could then be leveraged to track users even when JavaScript is completely disabled. "This is a side-channel attack which doesn't require any JavaScript to run," the...
