CVE-2025-5222 is a stack-based buffer overflow in International Components for Unicode (ICU). During execution of the genrb utility, the subtag structure can overflow in SRBRoot::addTag, potentially causing memory corruption and local arbitrary code execution. ICU version 76.0.1 is explicitly identified as affected; vulnerable ICU packages are also present in multiple downstream distributions and products.
