CVE-2024-20106
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 m4u, there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS08960505; Issue ID: MSV-1590.
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 confidenceIn the m4u driver, there is a possible out of bounds write due to a missing bounds check. This memory corruption vulnerability can lead to local privilege escalation from System execution privileges needed. User interaction is not required for exploitation.

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.
-
Check Android versionRun 'getprop ro.build.version.release' or check Settings > About Phone > Android version to determine the installed Android OS versionAffected if Version is 12.0, 13.0, 14.0, or 15.0 and the m4u driver is present on the device
-
Verify m4u driver presenceCheck if the m4u driver module exists on the system by searching for m4u-related files: 'find / -name '*m4u*' 2>/dev/null' or check /proc/modules for loaded m4u moduleAffected if The m4u driver is loaded or present on the device
-
Check security patch levelRun 'getprop ro.build.version.security_patch' to retrieve the security patch date applied to the systemAffected if The security patch level is earlier than the vendor patch ALPS08960505 release date, indicating the fix is not applied
-
Inspect m4u driver versionIf the driver module is found, run 'modinfo <m4u_module_path>' or check driver metadata for version/date informationAffected if The m4u driver version predates the fix for CVE-2024-20106
The device is affected if it runs Android 12.0, 13.0, 14.0, or 15.0 with the m4u driver present and the security patch level does not include the vendor fix ALPS08960505.

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.
dbcve · scopedApply vendor patch ALPS08960505 and update system software containing the m4u driver to include the bounds check fix.
- Contact your device manufacturer (OEM) to confirm they have integrated MediaTek patch ALPS08960505 into their Android security update
- Verify that your device's monthly security patch level is at least January 2024 or later (when the fix was likely released)
- Apply the OEM-provided system update containing the MediaTek m4u security fix
- If your OEM has not released a patch for this vulnerability, consider migrating to a device model that receives timely security updates
