Attack-Flow Graph

Executive Summary

This vulnerability is a use-after-free issue in the bigo_worker_thread function of the private/google-modules/video/gchips/bigo.c file. It occurs due to a race condition, which means that the program may access memory after it has been freed. This flaw can be exploited locally to escalate privileges without needing any additional execution privileges or user interaction.

Impact Analysis

The vulnerability can lead to local escalation of privilege, allowing an attacker who already has local access to the system to gain higher privileges. This could enable the attacker to perform unauthorized actions or access sensitive information on the affected device.

Mitigation Strategies

Users should update their Google Pixel devices to the latest firmware including the December 2025 security patch level or later to mitigate this vulnerability. [1]
