CVE-2026-20482: CWE-770 Allocation of Resources Without Limits or Throttling in MediaTek, Inc. MediaTek chipset
CVE-2026-20482 is a vulnerability in the wlan STA firmware of MediaTek chipsets MT7902, MT7921, MT7922, and MT8532. The issue involves allocation of resources without limits or throttling, causing the system to potentially become unresponsive due to excessive logging. This can lead to a remote denial of service (DoS) without requiring user interaction or additional privileges.
AI Analysis
Technical Summary
This vulnerability (CWE-770) affects the wlan STA firmware in specific MediaTek chipsets, where uncontrolled resource allocation related to logging can cause the system to become unresponsive. Exploitation can be performed remotely by an adjacent or proximal attacker, resulting in denial of service without needing elevated privileges or user interaction. The affected chipsets are MT7902, MT7921, MT7922, and MT8532. There is no CVSS score or vendor advisory indicating a patch or remediation level at this time.
Potential Impact
An attacker in proximity to the affected device can cause a denial of service by triggering excessive logging that exhausts system resources, leading to system unresponsiveness. No additional execution privileges or user interaction are required for exploitation. This impacts device availability but does not indicate privilege escalation or data compromise.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary mitigation has been documented at this time. Users and administrators should monitor MediaTek advisories for updates and apply patches once available.
