CVE-2026-20496: CWE-125 Out-of-bounds Read in MediaTek, Inc. MediaTek chipset
CVE-2026-20496 is an out-of-bounds read vulnerability in the geniezone component of MediaTek chipsets. The flaw arises from a missing bounds check, potentially allowing local information disclosure. Exploitation requires the attacker to have already obtained System privilege, and no user interaction is needed. Multiple MediaTek chipset models are affected. No patch or official remediation has been confirmed yet.
AI Analysis
Technical Summary
This vulnerability (CVE-2026-20496) involves an out-of-bounds read (CWE-125) in the geniezone component of MediaTek chipsets due to a missing bounds check. An attacker with System privilege could exploit this flaw to read memory outside intended boundaries, leading to local information disclosure. The vulnerability affects specific MediaTek chipset models enumerated in the affectedVersions field. There is no CVSS score or vendor advisory indicating patch availability or remediation level at this time.
Potential Impact
The vulnerability allows an attacker with System privilege to perform an out-of-bounds read, potentially disclosing sensitive local information. Since System privilege is required, the impact is limited to scenarios where the attacker already has elevated access. No remote or user-interaction-based exploitation is indicated.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, ensure that System privileges are tightly controlled to prevent exploitation. Monitor vendor channels for updates related to Patch ID ALPS11036877 and Issue ID MSV-7132.
