Denx

Denx develops U-Boot, the widely embedded bootloader that initializes hardware and loads operating systems across embedded systems, IoT devices, and enterprise network infrastructure. Vulnerabilities affecting this vendor skew strongly toward critical-severity outcomes, reflecting the privileged execution context and memory-unsafe parsing inherent to low-level firmware code. The exposure recurs through memory-safety weakness classes including out-of-bounds writes, integer overflows and underflows, and classic buffer overflows that arise from the bootloader's direct hardware interaction and minimal runtime constraints. Because U-Boot sits in the firmware boot chain of countless embedded devices, its flaws can compromise systems before the operating system loads, making timely remediation essential for defenders managing heterogeneous device inventories. Current severity, exploitation activity, and exposure counts are shown alongside this summary.
