Last modified

CVE-2024-25076 is a medium-severity vulnerability rated 6.8/10 on the CVSS scale. An issue was discovered on Renesas SmartBond DA14691, DA14695, DA14697, and DA14699 devices. The bootrom function responsible for validating the Flash Product Header directly uses a user-controllable size value (Length of Flash Config Section) to control a read from the QSPI device into a fixed sized buffer, resulting in a buffer overflow and execution of arbitrary code.. EPSS estimates a 0.40% chance of exploitation in the next 30 days.
