CVE-2026-40446
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAccess of resource using incompatible type ('type confusion') vulnerability in Samsung Open Source Escargot allows Pointer Manipulation.This issue affects Escargot: 97e8115ab1110bc502b4b5e4a0c689a71520d335.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceType confusion vulnerability in Samsung's Escargot JavaScript engine allows attacker-controlled type mismatches to manipulate memory pointers. This can lead to arbitrary memory read/write and potentially remote code execution.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Escargot installationSearch for Escargot binary or library files on the system. Common locations include /usr/bin/, /usr/lib/, or project directories. Look for files named 'escargot' or 'libescargot*'.Affected if Escargot is found on the system
-
Determine Escargot versionRun 'escargot --version' or check the library version if used as a shared library (e.g., 'ldd' or file metadata). Compare the version string to the affected version 2026-03-28.Affected if Version is exactly 2026-03-28
-
Verify the vulnerable component is in useCheck if any application or service is configured to use Escargot as its JavaScript engine. Look for configuration files, startup scripts, or application logs referencing Escargot.Affected if Escargot is actively loaded or executed by any application on the host
-
Check for code using Escargot APIsReview source code or binaries of applications that may embed Escargot. Search for Escargot API usage patterns (e.g., 'EscargotEngine', 'executeScript').Affected if Applications are using Escargot's JavaScript execution APIs
A system is affected only if Escargot version 2026-03-28 is installed and actively used as the JavaScript engine.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpdate Escargot to a version after commit 97e8115ab1110bc502b4b5e4a0c689a71520d335 that includes proper type checking fixes, or apply source-level patches to add runtime type validation before pointer operations.
