+## Add Kernel Address Sanitizer functionality to coreboot
+The Kernel Address Sanitizer (KASAN) is a runtime dynamic memory error detector.
+The idea is to check every memory access (variables) for its validity
+during runtime and find bugs like stack overflow or out-of-bounds accesses.
+Implementing this stub into coreboot like "Undefined behavior sanitizer support"
+would help to ensure code quality and make the runtime code more robust.
+
+### Requirements
+* knowledge in the coreboot build system and the concept of stages
+* the KASAN feature can be improved in a way so that the memory space needed
+ during runtime is not on a fixed address provided during compile time but
+ determined during runtime. For this to achieve a small patch to the GCC will
+ be helpful. Therefore minor GCC knowledge would be beneficial.
+* Implementation can be initially done in QEMU and improved on different
+ mainboards and platforms
