An original English rewrite of Alexandre Adamski’s 2021 Impalabs deep dive into Samsung’s Real-time Kernel Protection (RKP). The post walks through three independent vulnerabilities — CVE-2021-25415, CVE-2021-25416 and CVE-2021-25417 — that let a kernel-level attacker remap hypervisor memory as writable, sneak executable kernel pages through the “dynamic load” interface, and modify RKP-protected read-only kernel memory. All credit for the research belongs to the original author and Impalabs.
