CVE-2025-6202

Vulnerability in SK Hynix DDR5 on x86 allows a local attacker to trigger Rowhammer bit flips impacting the Hardware Integrity and the system's security. This issue affects DDR5: DIMMs produced from 2021-1 until 2024-12...

SK Hynix DDR5 安全漏洞

SK Hynix DDR5 is a double data rate synchronous dynamic random access memory from SK Hynix South Korea. A security vulnerability exists in SK Hynix DDR5 versions 2021-1 through 2024-12, which originates from a local attacker who can trigger a Rowhammer bit flip, potentially impacting hardware...

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...

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 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 access patterns to trigger bit...

CVE-2020-10255

The CVE-2020-10255/TRRRespass issue affects modern memory (DDR4/LPDDR4 after 2015) where Target Row Refresh mitigations can be bypassed by rowhammer patterns. Documents in connected sources confirm this can allow privilege escalation, kernel/Sudo compromise, and cross-tenant VM access via bit fli...

Walkthrough. Investigating an SSD

I had an interesting job come in. A client wants the data off a dead SSD, and it’s a model that regular data recovery companies won’t deal with, an SK Hynix drive. It’s used extensively on many Dell laptops. The drive is NVMe which means it uses several PCIe lanes for communication. First things...
