CVE-2024-20138Network attack vector

Remote information disclosure via improper WLAN input validation

Published Dec 2, 2024 · Updated Dec 2, 2024

Out-of-bounds read in MediaTek WLAN drivers for Android 13.0 through 15.0 and SDK 3.3 and earlier allows remote attackers to disclose data. The driver fails to validate an unspecified WLAN input before reading beyond a buffer boundary; MediaTek has not disclosed the function or input format. Exploitation needs no privileges or user interaction, and the documented consequence is disclosure of data readable beyond the intended buffer.
