The Impact of Non-Blocking Consoles (nbcon) on Linux Boot Time
During the Linux boot process, the boot console is responsible for relaying boot messages to the user. On embedded systems this console is often attached to a serial port that can only handle a maximum data rate of a few kilobytes per second which degrades overall boot time. In this post we’ll explore how the …

Exploiting a Buffer Overflow Vulnerability for Remote Code Execution in Nginx
Protecting devices from malicious use is often a cat-and-mouse game between security researchers identifying software vulnerabilities (CVEs) and product-makers patching them before attackers can exploit them. As a result, devices can no longer be developed, shipped and forgotten. Instead, manufacturers must commit to keeping those devices up to date and free from critical vulnerabilities for …
