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 mdp, there is a possible memory corruption due to a use after free. This could lead to local escalation of privilege with System execution privileges needed. User interaction is needed for exploitation. Patch ID: ALPS05836642; Issue ID: ALPS05836642.

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

A use-after-free vulnerability exists in the mdp (media display processor) component that allows local privilege escalation to System execution level. The vulnerability requires user interaction to trigger and involves memory corruption where freed memory is accessed after being deallocated. This is a memory safety issue in the display processing subsystem of the affected system.

MitigationApply vendor patch ALPS05836642 to address the use-after-free vulnerability in the mdp component. As this appears to be firmware-level, contact the device/vendor for the appropriate patch and ensure system privileges are not granted to untrusted applications.

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 OS version
    Go to Settings > About Phone > Android version or run 'getprop ro.build.version.release' via ADB shell
    Affected if Version is exactly 11.0 or 12.0 (note: only these specific versions are affected, not ranges)
  2. Verify vendor security patch level
    Check Settings > About Phone > Security patch level or run 'getprop ro.build.version.security_patch' via ADB shell
    Affected if Security patch level is earlier than the date when ALPS05836642 was released (contact device vendor for specific patch date)
  3. Confirm mdp component exposure
    This vulnerability exists in the mdp (media display processor) firmware component. On affected Android devices, this component handles display processing. There is no direct user-accessible method to check mdp version; this requires vendor-level diagnostics.
    Affected if Device runs Android 11.0 or 12.0 and the vendor has not applied the ALPS05836642 patch to the firmware

A user is affected if their device runs Android 11.0 or 12.0 and the vendor patch ALPS05836642 has not been applied to address the use-after-free in the mdp display processor component.

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

Apply vendor patch ALPS05836642 to address the use-after-free vulnerability in the mdp component. As this appears to be firmware-level, contact the device/vendor for the appropriate patch and ensure system privileges are not granted to untrusted applications.

Recommended fix High confidence
  1. Identify if your device uses a MediaTek chipset (check device specifications)
  2. Contact your device manufacturer (OEM) to confirm they have incorporated MediaTek patch ALPS05836642 to address this use-after-free vulnerability in the mdp component
  3. Check that your device has the latest Android security update installed (go to Settings > Security > Security patch level)
  4. If the patch is not available, monitor your device manufacturer's support channels for the forthcoming OTA update containing this fix
  5. Apply any available system updates promptly after verifying they come from your legitimate device manufacturer
