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 RtpSession::rtpSendRtcpPacket, there is a possible OOB write due to a heap buffer overflow. This could lead to remote code execution 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

A heap buffer overflow in RtpSession::rtpSendRtcpPacket allows out-of-bounds writes when processing RTCP packets, enabling remote code execution without user interaction or elevated privileges.

MitigationImplement strict bounds checking on RTCP packet size and contents before heap buffer writes in rtpSendRtcpPacket; validate packet length fields against actual buffer allocation.

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 RTP/RTCP-enabled applications
    Run 'ps -A | grep -i rtp' or check /proc/<pid>/fd for socket connections using RTP/RTCP protocols (typically UDP ports in range 5000-6000)
    Affected if Any application is using RTP/RTCP sockets or libraries
  2. Locate RtpSession library
    Search for libjrtp.so, libortp.so, or similar RTP libraries in /system/lib/ or /vendor/lib/ using 'find /system/lib -name "*rtp*"'
    Affected if RTP library containing RtpSession component is present on the device
  3. Verify RTCP processing is active
    Capture network traffic with tcpdump or ss -uanp to detect RTCP packets (port 5001 typically) flowing to/from the device
    Affected if RTCP packets are being sent or received by the device
  4. Check for RTP service configurations
    Examine /etc/ or /system/etc/ for RTP/RTCP configuration files, or check app manifests for android.permission.INTERNET usage with RTP intent filters
    Affected if Any service or application is configured to process RTP streams with RTCP feedback enabled
  5. Inspect process memory for RtpSession usage
    For running processes, check /proc/<pid>/maps for mmap of RTP libraries and review logcat output for 'RtpSession' or 'RTCP' tag messages
    Affected if A process has loaded an RTP library and is actively processing RTCP packets

If any application on the Android device is actively sending or receiving RTCP packets using an RtpSession component, the device is vulnerable to heap buffer overflow exploitation during RTCP packet processing.
