CVE-2020-35608

Estado: ModificadaAlta (7.8)—

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.
