CVE-2026-20451: CWE-843 Access of Resource Using Incompatible Type ('Type Confusion') in MediaTek, Inc. MediaTek chipset
In slbc, there is a possible out of bounds write due to type confusion. This could lead to local escalation of privilege if a malicious actor has already obtained the System privilege. User interaction is not needed for exploitation. Patch ID: ALPS10828685; Issue ID: MSV-6504.
AI Analysis
Technical Summary
This vulnerability involves a type confusion flaw (CWE-843) in the slbc component of various MediaTek chipsets, which can result in an out-of-bounds write. The issue could be exploited locally by an attacker who already has System privileges to escalate their privileges further. The affected chipsets include a broad range of MediaTek models such as MT2718, MT6899, MT6985, and others. There is no indication of user interaction being required for exploitation. No official patch or remediation level has been provided yet, and no known exploits are reported in the wild.
Potential Impact
The vulnerability allows a local attacker with existing System privileges to perform an out-of-bounds write due to type confusion, potentially escalating their privileges further. This could compromise system integrity on affected MediaTek chipsets. There is no evidence of remote exploitation or exploitation without prior elevated privileges. No known exploits have been reported in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official patch or remediation level has been published, users and administrators should monitor MediaTek advisories for updates. No specific mitigations or workarounds are currently documented.
