New Phoenix RowHammer Attack Overcomes DDR5 Memory Protections in Just 109 Seconds
A research team from ETH Zürich and Google has unveiled a new variant of the RowHammer attack, named Phoenix, specifically targeting DDR5 memory chips produced by SK Hynix. This attack (CVE-2025-6202, CVSS score: 7.1) effectively circumvents advanced security measures designed to protect against such vulnerabilities. “Our findings confirm that it is possible to consistently trigger RowHammer bit flips on a wider scale with SK Hynix’s DDR5 devices,” stated ETH Zürich’s Computer Security Group (COMSEC). “We also demonstrated that on-die ECC fails to prevent RowHammer attacks, making end-to-end RowHammer exploits feasible on DDR5.” RowHammer is a critical hardware vulnerability where repetitive access to a memory row can induce bit flips in neighboring rows, leading to data corruption that malicious actors can exploit to access sensitive information or elevate privileges.
New Phoenix RowHammer Attack Compromises DDR5 Memory Protections A recent discovery made by researchers from ETH Zürich and Google has brought to light a new variant of the RowHammer attack, specifically targeting DDR5 memory chips from South Korean semiconductor manufacturer SK Hynix. This variant, dubbed Phoenix (CVE-2025-6202, CVSS score: 7.1),…
