A code execution vulnerability exists in the normal world’s signed code execution functionality of Microsoft Azure Sphere 20.07. A specially crafted AF_PACKET socket can cause a process to create an executable memory mapping with controllable content. An attacker can execute a shellcode that uses the PACKET_MMAP functionality to trigger this vulnerability.

Weakness

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
