# Android Trusty: out-of-bounds read in shared memory manager leaks data locally

Link for people: https://infrastack.ai/live/CVE-2026-55348 (this .md is for agents)

A sign-extension error in the Trusty shared memory manager lets a negative buffer size cause an out-of-bounds read. An attacker with System-level code on the device could read memory they should not see.

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

## From the sources

In GetSharedMemory of trusty_shared_memory_manager.cc, there is a possible way to trigger an out of bounds read via sign extension of a negative buffer size due to an improper or implicit cast. This could lead to local information disclosure with System execution privileges needed. User interaction is not needed for exploitation.
