Researchers at Binarly have identified six new vulnerabilities in U-Boot, the bootloader responsible for starting various hardware devices, including routers and smart cameras. Four of these flaws can cause devices to crash, while two others could allow attackers to execute their own code by presenting a malicious image to the bootloader. This is particularly concerning as U-Boot is widely used across many platforms, making a large number of devices potentially vulnerable. If exploited, these vulnerabilities could lead to unauthorized access and control over affected systems before they even fully boot up. Users and manufacturers need to be aware of these vulnerabilities to ensure their devices remain secure.
