Code execution via unchecked flash configuration length
Published Jul 10, 2024 · Updated Aug 1, 2024
Buffer overflow in the DA1469x secure-boot ROM on Renesas DA14695 devices allows physically proximate attackers to execute code. The Flash Product Header validator uses the attacker-controlled Length of Flash Config Section to read QSPI data into a fixed-size buffer without checking the destination capacity. Physical access to the flash device is required; successful exploitation defeats secure boot and runs injected code on the device.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
