CVE-2026-20482: CWE-770 Allocation of Resources Without Limits or Throttling in MediaTek, Inc. MediaTek chipset
CVE-2026-20482 is a medium severity vulnerability in MediaTek chipset WLAN STA firmware that can cause the system to become unresponsive due to uncontrolled logging. This issue can be exploited remotely by an adjacent attacker without requiring user interaction or additional privileges, resulting in a denial of service condition.
AI Analysis
Technical Summary
This vulnerability involves an allocation of resources without limits or throttling (CWE-770) in the WLAN STA firmware of MediaTek chipsets MT7902, MT7921, MT7922, and MT8532. Excessive logging can cause the system to become unresponsive, leading to a denial of service. The flaw can be triggered remotely by an attacker in proximity without needing user interaction or elevated privileges. No patch or official remediation level has been confirmed in the provided data.
Potential Impact
An attacker within adjacent network range can cause the affected MediaTek chipset to become unresponsive, resulting in denial of service. There is no impact on confidentiality or integrity, and no additional execution privileges are required for exploitation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a patch is available, consider limiting exposure to adjacent network attackers through network segmentation or access controls where feasible.
