Analysis Summary
# Vulnerability: Zero-Day Exploitation in Android Kernel and System Components
## CVE Details
- CVE ID: CVE-2024-53197, CVE-2024-53150
- CVSS Score: Not explicitly stated (Implied High due to active exploitation)
- CWE: Not specified in detail (One flaw is in the kernel)
## Affected Systems
- Products: Android Operating System
- Versions: Unspecified vulnerable versions patched in the April 2025 bulletin.
- Configurations: General Android devices.
## Vulnerability Description
Google patched two zero-day flaws in Android that were reportedly under "limited, targeted exploitation."
1. **CVE-2024-53197:** This vulnerability was identified by Amnesty International and Google's TAG concerning exploitation chains used by Cellebrite devices targeting a Serbian student activist. The specific technical details were not provided in this summary, but it was part of a chain used for sophisticated device compromise.
2. **CVE-2024-53150:** This flaw was found specifically within the Android **Kernel**.
## Exploitation
- Status: Actively exploited in limited, targeted scenarios (Zero-day).
- Complexity: Implied Medium/High due to targeting and use in complex exploit chains (especially CVE-2024-53197).
- Attack Vector: Technical details lacking, but associated activity implies Network or Local access might be necessary depending on the specific exploit chain.
## Impact
*Note: Specific impact scores are not provided in the source, but active zero-day use implies High potential impact.*
- Confidentiality: Undetermined (Likely High given the context of surveillance targeting)
- Integrity: Undetermined (Likely High)
- Availability: Undetermined (Likely Low to Medium)
## Remediation
### Patches
- Patches were released by Google in an update on Monday (April 7th or 8th, 2025), referencing the Android Security Bulletin for April 2025. (Specific patch versions are not detailed in the summary.)
### Workarounds
- No specific workarounds were mentioned in the provided text, other than applying the official update.
## Detection
- Detection methods are not specified, but the context suggests these vulnerabilities were leveraged by sophisticated actors (law enforcement/Cellebrite users). Users should monitor for indicators related to suspicious process execution or unexpected data exfiltration patterns associated with targeted attacks.
