CVE-2026-47310

Pointer manipulation via stale finalizer source

Published May 19, 2026 · Updated May 19, 2026

Use-after-free in Samsung Escargot 590345cc6258317c5da850d846ce6baaf2afc2d3 allows local users to manipulate pointers via crafted JavaScript. Unordered garbage-collector finalizers can collect a FinalizationRegistry before its targets, causing a target finalizer to dereference the registry through a stale source pointer. Exploitation requires local execution and user interaction; successful pointer manipulation can compromise process data or crash the hosting process.
