FKIE_CVE-2026-20528
Vulnerability from fkie_nvd - Published: 2026-10-05 02:16 - Updated: 2026-10-09 15:03
Severity
Summary
In ccci, there is a possible out of bounds write and read due to a missing bounds check. This could lead to local information disclosure, memory corruption, crashes, or privilege escalation if a malicious actor has already obtained the System privilege. User interaction is needed for exploitation. Patch ID: ALPS11428950 (Note: For MT6880, MT6890) / ALPS10563453 (Note: For MT6980D, MT6990, MT6986, MT6986D, MT6813, MT6988) / AUTO00858766 (Note: For MT2735, MT2737); Issue ID: MSV-9893.
