CVE-2026-86314

Integer overflow in the source-bounds check in Memory::init() (src/runtime/Memory.cpp) in Samsung walrus on all platforms allows a remote attacker to cause an out-of-bounds heap read and denial of service via a crafted WebAssembly module in which a 32-bit unsigned addition wraps around and bypasses the bounds check. This issue affects Walrus: ff3bf5ff5c4878f8e5572c9593d303f6bc997443.

Summary		(es) Desbordamiento de entero en la comprobación de límites de origen en Memory::init() (src/runtime/Memory.cpp) en Samsung walrus en todas las plataformas permite a un atacante remoto causar una lectura de montón fuera de límites y denegación de servicio a través de un módulo WebAssembly manipulado en el que una suma sin signo de 32 bits se desborda y omite la comprobación de límites. Este problema afecta a Walrus: ff3bf5ff5c4878f8e5572c9593d303f6bc997443.
