CVE-2026-47308: Samsung Walrus NULL pointer dereference

CVE-2026-47308 · Severity: medium · CVSS 5.5 · Published 2026-05-19

Technologies: Samsung Walrus. Vendors: Samsung.

Executive brief

Samsung Walrus, an open-source library, is affected by a software flaw that can lead to application crashes. If an attacker provides a specially crafted input, they can trigger a memory error that forces the program to stop responding. This primarily impacts the reliability and availability of services using the library, though it does not directly lead to data theft.

Technical details

A NULL pointer dereference (CWE-476) exists in Samsung Open Source Walrus at commit f339b8e. The vulnerability is triggered when the software attempts to read or write to a memory address that is expected to be valid but is actually NULL, leading to a crash. An attacker can exploit this via local access by providing malicious input that requires user interaction (UI:R). This results in a high impact on availability but does not affect confidentiality or integrity. A fix was introduced in pull request #409 to improve error throwing and resource limit handling.
