Summary

An integer overflow in the source-bounds check in Memory::init() 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 where a 32-bit unsigned addition wraps around and bypasses the bounds check.

Risk Assessment

The vulnerability may lead to system crashes or memory data leakage. Remote unauthenticated attack increases the risk.

Recommendation

Update to a patched version or apply available fixes. Limit trust in WebAssembly modules.
