The flaw exists in how the kernel handles memory pages when processing ESP encrypted network packets. An attacker can craft a packet that causes the kernel to decrypt data directly into memory pages it does not own, including the cached copies of privileged operating system binaries. When one of those binaries is executed, the attacker's injected code runs with root privileges. In APM Edge, the vulnerable kernel modules (esp4, esp6) can be loaded by any local user and exploited.
