EPSS · scored 2026-10-27

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.
