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 · unedited
In 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 confidence

In 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.

MitigationApply vendor patch ALPS08960505 and update system software containing the m4u driver to include the bounds check fix.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Check Android version
    Run 'getprop ro.build.version.release' or check Settings > About Phone > Android version to determine the installed Android OS version
    Affected if Version is 12.0, 13.0, 14.0, or 15.0 and the m4u driver is present on the device
  2. Verify m4u driver presence
    Check 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 module
    Affected if The m4u driver is loaded or present on the device
  3. Check security patch level
    Run 'getprop ro.build.version.security_patch' to retrieve the security patch date applied to the system
    Affected if The security patch level is earlier than the vendor patch ALPS08960505 release date, indicating the fix is not applied
  4. Inspect m4u driver version
    If the driver module is found, run 'modinfo <m4u_module_path>' or check driver metadata for version/date information
    Affected 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.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Apply vendor patch ALPS08960505 and update system software containing the m4u driver to include the bounds check fix.

Recommended fix Moderate confidence
  1. Contact your device manufacturer (OEM) to confirm they have integrated MediaTek patch ALPS08960505 into their Android security update
  2. Verify that your device's monthly security patch level is at least January 2024 or later (when the fix was likely released)
  3. Apply the OEM-provided system update containing the MediaTek m4u security fix
  4. If your OEM has not released a patch for this vulnerability, consider migrating to a device model that receives timely security updates
