Local information disclosure via content-provider permissions bypass
Published Jan 24, 2023 · Updated Apr 2, 2025
Information disclosure in Google Cloud Android kernel ShannonRcs allows local users to read protected content-provider data. ShannonRcs exports content providers while assigning permissions that fail to enforce protection on providers reached through them. A low-privileged local context is required, no user interaction is needed, and disclosure is the only documented consequence.
