Unpatched Critical Flaws Disclosed in U-Boot Bootloader for Embedded Devices

Cybersecurity researchers have disclosed two unpatched security vulnerabilities in the open-source U-Boot boot loader. The issues, which were uncovered in the IP defragmentation algorithm implemented in U-Boot by NCC Group, could be abused to achieve arbitrary out-of-bounds write and denial-of-service (DoS). U-Boot is a boot loader used in Linux-based embedded systems such as ChromeOS as well as
