What is CVE-2024-6287?

An incorrect calculation vulnerability in Renesas Arm-Trusted-Firmware poses a significant security risk by allowing local execution of code. This vulnerability arises from the firmware's failure to accurately assess whether a new image overlaps with a previously loaded image. An attacker can exploit this flaw to bypass memory range restrictions, enabling them to partially or completely overwrite an already loaded image. The consequences include unauthorized code execution and a potential bypass of secure boot mechanisms, which are critical for maintaining the integrity of secure environments.
