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 Write of msg_to_host_buffer.cc, there is a possible out of bounds write due to an incorrect bounds check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.

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 msg_to_host_buffer.cc file, a buffer write operation performs an incorrect bounds check, allowing an out-of-bounds write. This memory corruption vulnerability can be exploited locally to escalate privileges to higher authority levels without requiring user interaction or additional execution privileges.

MitigationApply the vendor-supplied patch that corrects the bounds check logic in msg_to_host_buffer.cc to prevent the out-of-bounds write condition.

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. Identify the component containing msg_to_host_buffer.cc
    Search the Android system for the msg_to_host_buffer.cc file or its compiled binary. Use 'find / -name msg_to_host_buffer.cc 2>/dev/null' or check known Android system component directories.
    Affected if The file is present in the system, indicating the vulnerable component is installed.
  2. Determine the installed component version
    Query the package manager or system properties for the version of the component that contains msg_to_host_buffer.cc. For example: 'dumpsys package <package_name>' or check build.prop for system version information.
    Affected if The component version matches or falls within an unpatched version range for this CVE.
  3. Verify if the vulnerable buffer write code path exists
    If possible, inspect the compiled binary or check the source for the specific bounds check logic in msg_to_host_buffer.cc that performs the incorrect bounds check during buffer write operations.
    Affected if The vulnerable bounds check code is present in the installed version.
  4. Check for available security patches
    Review the Android security patch level by checking 'Settings > About Phone > Security Patch Level' or running 'getprop ro.build.version.security_patch'. Compare against the patch date for CVE-2026-0153.
    Affected if The installed security patch level predates the CVE-2026-0153 fix date.

A user is affected if the vulnerable component containing msg_to_host_buffer.cc is present and the installed Android version lacks the CVE-2026-0153 patch.
