CVE-2026-20488: CWE-125 Out-of-bounds Read in MediaTek, Inc. MediaTek chipset
CVE-2026-20488 is an out-of-bounds read vulnerability (CWE-125) in MediaTek chipsets that may lead to local information disclosure. The flaw exists in the display component due to a missing bounds check. 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 information is currently available.
AI Analysis
Technical Summary
This vulnerability involves an out-of-bounds read in the display functionality of MediaTek chipsets caused by a missing bounds check. It can result in local information disclosure if a malicious actor with System privileges exploits it. The vulnerability affects specific MediaTek chipset models listed explicitly. There is no CVSS score or vendor advisory indicating a patch or mitigation status at this time.
Potential Impact
An attacker with System privilege on an affected MediaTek chipset could exploit this vulnerability to read memory out-of-bounds, potentially disclosing sensitive information locally. Since System privilege is required, the impact is limited to scenarios where such privilege is already obtained. 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. No official fix or mitigation has been published. Until a patch is available, ensure that System privileges are tightly controlled to prevent exploitation.
