Vulnerability from fkie_nvd - Published: 2026-09-07 03:17 - Updated: 2026-09-07 03:17
Severity
6.2 (Medium) - CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Summary
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.
