Samsung Open Source Escargot Vulnerability: Use-After-Free Allows Pointer Manipulation
The National Vulnerability Database has disclosed CVE-2026-47310, a high-severity use-after-free vulnerability affecting Samsung Open Source Escargot. Specifically, Escargot version 590345cc6258317c5da850d846ce6baaf2afc2d3 is susceptible to pointer manipulation, scoring a CVSS 3.1 of 7.8 (High).
This class of vulnerability, CWE-416, is critical because it allows an attacker to execute arbitrary code or cause a denial of service by manipulating memory after it has been freed. The attacker’s calculus here is clear: gain control over freed memory, then redirect execution flow or corrupt data. While the attack vector is local (AV:L) and requires user interaction (UI:R), the high impact on confidentiality, integrity, and availability (C:H/I:H/A:H) means successful exploitation can be devastating.
Defenders need to treat use-after-free vulnerabilities with extreme prejudice. When exploited, these bugs often lead to reliable arbitrary code execution. Organizations leveraging Samsung Open Source Escargot in their environments must identify if they are running the affected commit and prioritize patching or mitigation. This isn’t theoretical; this is a direct path for an adversary to gain deep system control.
What This Means For You
- If your organization integrates or uses Samsung Open Source Escargot, specifically version `590345cc6258317c5da850d846ce6baaf2afc2d3`, you are exposed to CVE-2026-47310. Immediately identify your Escargot versions and apply any available patches or workarounds to prevent pointer manipulation and potential arbitrary code execution.
