Phoenix — an attack on DDR5 chips leading to memory content corruption
Researchers from the Swiss Federal Institute of Technology Zurich, in collaboration with engineers from Google, have developed a new Rowhammer attack technique—Phoenix (CVE-2025-6202)—that bypasses the TRR (Target Row Refresh) protection mechanisms used in DDR5 chips, which prevent cell corruption due to charge loss. A proof-of-concept exploit has been published that allows modification of a specific bit in RAM and achieves an increase in […]
