What is CVE-2023-35659?

A logic error in the devicemem_server.c file of the Android kernel can lead to arbitrary code execution. This issue allows attackers to escalate privileges locally within the kernel without any need for additional execution privileges or user interaction, potentially compromising system integrity and security. The vulnerability is linked to the DevMemIntChangeSparse function, which fails to handle certain conditions correctly, thereby exposing the system to unauthorized access.
