CVE-2026-21038

Out-of-Bounds Memory Access in Samsung Android USB Driver for Windows

Published Jun 5, 2026 CVSS 4.0 · 5.9 Medium EPSS < 1% KEV · Not listed
Description
Improper input validation in Samsung Android USB Driver for Windows prior to version 1.9.5.0 allows local attacker to access out-of-bounds memory.

Analysis

AI-generated

Technical impact

The vulnerability is caused by improper input validation in the Samsung Android USB Driver for Windows before version 1.9.5.0. An attacker who can supply crafted input to the driver can cause the driver to read or otherwise access memory beyond the intended bounds, potentially leading to memory corruption, application or driver crashes, and possibly escalation of privileges if the driver runs with high privileges. The weakness is a classic input validation flaw that can result in out-of-bounds memory access.

Affected Systems

On Windows systems that have the Samsung Android USB Driver for Windows installed, any version earlier than 1.9.5.0 is vulnerable. The driver is used to connect Samsung Android devices via USB, and administrators should verify which installed version is present on each workstation or server.

Risk and Exploitability

The CVSS score of 5.9 indicates moderate severity. The EPSS score of < 1% and the fact that the vulnerability is not listed in CISA’s KEV catalog suggest a limited but non-negligible risk of exploitation. The attack vector is local: an attacker must be able to run code on the affected machine to supply the malicious data. Without a verified exploit or documented impact beyond corruption, the likelihood of successful exploitation remains uncertain, but because the driver often runs with elevated privileges, the potential impact should not be ignored.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update the Samsung Android USB Driver to version 1.9.5.0 or later, which resolves the input validation flaw
  • If an update is not immediately available, restrict physical access to the device or remove the USB driver from systems that do not require it
  • Monitor for any anomalous activity or crashes that could indicate exploitation of the memory corruption vulnerability
