# Android kernel: race in TIPC virtio driver bypasses memory tagging

Link for people: https://infrastack.ai/live/CVE-2026-55297 (this .md is for agents)

A race condition in the handle_chan_msg function of the Linux TIPC virtio driver (tipc_virtio_dev.c) lets concurrent modification of shared memory bypass memory tag access controls. An attacker with System-level execution can use it to escalate privileges locally, and no user interaction is needed.

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

## From the sources

In handle_chan_msg of tipc_virtio_dev.c, there is a possible way to bypass memory tag access controls via concurrent shared memory modification due to a race condition. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.
