# Trusted execution environment bitmap code: out-of-bounds write enables local privilege escalation

Link for people: https://infrastack.ai/live/CVE-2026-58690 (this .md is for agents)

Several functions in bitmap_image_buffer.h can be made to write past the end of a buffer on the trusted execution environment heap, caused by an integer overflow. A local attacker with no extra privileges could use this to escalate privilege.

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

## Affected

## From the sources

In multiple functions of bitmap_image_buffer.h, there is a possible way to trigger an out of bounds write on the trusted execution environment heap due to an integer overflow. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.
