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 display drm, there is a possible memory corruption due to a race condition. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07363469; Issue ID: ALPS07363469.

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 race condition in the Linux kernel's Direct Rendering Manager (DRM) display subsystem can cause memory corruption, potentially allowing a local attacker with System-level privileges to escalate to full root privileges. The vulnerability stems from improper synchronization in the display driver code, where concurrent access to shared memory structures is not adequately protected.

MitigationApply the vendor patch ALPS07363469 to the affected kernel/display driver. This is a MediaTek/ARM Mali panel driver patch; verify your system uses this component and apply the update through standard kernel patching procedures.

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
    Affected if The version is 11.0, 12.0, or 13.0 exactly (these are the affected versions per the CVE)
  2. Identify the display driver in use
    Check /proc/cmdline for kernel parameters, or examine /sys/class/drm for card0/device/driver to see which DRM driver is loaded
    Affected if The driver is MediaTek Mali or ARM Mali panel driver (this is the specific component with the race condition)
  3. Check kernel build information
    Run 'uname -a' or check /proc/version to retrieve the kernel version and build details
    Affected if The kernel is built from Android common kernel branches for 11.0, 12.0, or 13.0 and includes the MediaTek Mali display subsystem
  4. Verify the DRM subsystem components
    Examine /sys/module/ directory for loaded DRM-related modules: ls /sys/module/ | grep -E 'mali|drm|panel'
    Affected if A Mali GPU or panel driver module is loaded and the system runs an affected Android version

A system is affected if it runs Android 11.0, 12.0, or 13.0 and uses a MediaTek/ARM Mali display driver component, where concurrent display driver access can trigger the race condition.
