CVE-2024-20101
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn wlan driver, there is a possible out of bounds write due to improper input validation. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS08998901; Issue ID: MSV-1602.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA critical out-of-bounds write vulnerability exists in the WLAN driver due to improper input validation, allowing remote code execution without requiring any user interaction or elevated privileges. The flaw stems from insufficient validation of input data passed to the driver, enabling an attacker to write data beyond allocated buffer boundaries.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Mediatek SDK version in useCheck system information or firmware metadata for the Mediatek Software Development Kit version number. This is typically found in build files, system properties, or firmware manifests depending on the device implementation.Affected if The SDK version is 3.3 or any version lower than 3.3
-
Determine Android OS versionOn the Android device, go to Settings > About Phone > Android version, or use 'getprop ro.build.version.release' via ADB shell.Affected if The Android version is 13.0, 14.0, or 15.0
-
Confirm Mediatek WLAN driver is presentCheck for Mediatek wireless driver modules or firmware files on the system. On Linux-based systems, examine /lib/firmware or /system/vendor/firmware for Mediatek WLAN-related files. On Android, use 'getprop' to query for Mediatek WLAN properties.Affected if Mediatek WLAN driver or firmware is loaded on the device
-
Verify wireless interface is enabledCheck if a wireless network interface exists and is active using 'ip link show' or 'iwconfig' commands. The vulnerability requires the WLAN driver to be loaded and the wireless subsystem to be operational.Affected if A wireless interface managed by the Mediatek WLAN driver is present and active
A system is affected if it uses Mediatek SDK version 3.3 or below OR runs Android 13.0/14.0/15.0 with an active Mediatek WLAN driver present.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the vendor patch ALPS08998901 immediately to affected systems, as this driver-level vulnerability can be exploited remotely without user interaction.
