# Android media stack: heap overflow in RTP text encoder allows remote code execution

Link for people: https://infrastack.ai/live/CVE-2026-56956 (this .md is for agents)

A logic error in the T.140 text encoder of TextRtpPayloadEncoderNode.cpp can cause a heap buffer overflow. The sources say this could lead to remote code execution with no extra privileges and no user interaction.

_Summary, check and fix written by a model from the sources; labelled as such._

## From the sources

In EncodeT140 of TextRtpPayloadEncoderNode.cpp, there is a possible Heap Buffer Overflow due to a logic error in the code. This could lead to remote code execution with no additional execution privileges needed. User interaction is not needed for exploitation.
