Detailsinfo

A vulnerability was found in Samsung Walrus (affected version not known) and classified as problematic. Affected by this issue is the function Memory::init of the file src/runtime/Memory.cpp of the component Memory. The manipulation with an unknown input leads to a integer overflow vulnerability.
