Rowhammer is an exploit that causes memory cells to leak their charges and interact electrically between themselves, possibly altering the contents of nearby memory rows that were not originally addressed.
The row hammer effect has been used in some privilege escalation computer security exploits. Different hardware-based techniques exist to prevent the row hammer effect from occurring, including required support in some processors and types of DRAM memory modules.
Essentially this exploit can gain root access to the kernel.
It is said that this exploit can spread from an x86-x64 architecture and android to an ARM architecture.
