Android zero-day vulnerabilities were patched in Google’s December 2025 Android Security Bulletin after confirmed in-the-wild exploitation.
Google shipped fixes across core frameworks, system, kernel, and vendor components. Users and enterprises should prioritize installation once updates appear.
Pixel devices typically receive updates first, followed by OEM rollouts. Refer to official bulletins for coverage and timing.
Android Zero-Day Vulnerabilities: What You Need to Know
- Google fixed two exploited flaws and dozens more issues; patch immediately.
Supplement patching with layered defenses:
Bitdefender — Anti-malware to block exploitation attempts.
1Password — Enterprise password manager with phishing protections.
IDrive — Encrypted cloud backup for resilient recovery.
Tresorit — End-to-end encrypted storage for sensitive data.
What Google fixed and why it matters
Google confirmed two Android zero-day vulnerabilities were exploited before patches shipped. While Google withheld deep technical detail pending patch adoption, the confirmation signals viable attack chains targeting Android devices.
When Android zero-day vulnerabilities are active, rapid updates and strong endpoint controls are essential to blunt exploitation.
The December release also delivers broad fixes across frameworks, system services, kernel, and vendor code. Even devices not directly exposed to the exploited paths benefit, since attackers often chain nearby weaknesses.
Closing these gaps reduces lateral movement opportunities and lowers follow-on compromise risk.
Who is affected
All supported Android devices should install the update when available from Google or the device manufacturer. Pixel users and enterprise fleets will see staged rollouts that may take days or weeks.
During this window, Android zero-day vulnerabilities can still affect unpatched endpoints in mixed environments.
Review authoritative guidance here: Android Security Bulletin and Pixel Update Bulletin.
Update availability and rollout tips
Install from Settings > Security & privacy > System & updates once the patch appears. Use MDM or EMM to force update windows, track compliance, and quarantine laggards. Assume partial exposure to Android zero-day vulnerabilities until every endpoint completes installation.
Reinforce account hygiene and password strength while updates propagate. For context on password cracking speed, see this explainer (learn more).
What about Pixel devices?
Pixel owners typically receive updates first. The Android Pixel security patch December 2025 targets prompt delivery of all relevant fixes and security patch levels. For cadence context, see prior coverage of monthly updates (January 2025 Android updates).
Continue monitoring managed devices for anomalies until the rollout completes, and pair updates with vetted password managers when appropriate (1Password review).
CVEs and tracking
Security teams should track CVEs in the monthly bulletin to prioritize remediation beyond the headlines. The NIST National Vulnerability Database provides details and scoring: NVD.
Researchers may reference items such as the CVE-2024-43047 Android vulnerability in related advisories. CVE identifiers streamline triage, cross-team communication, and validation of mitigations tied to Android zero-day vulnerabilities.
Security implications of December’s fixes
Advantages: Fast installation lowers exposure to active exploitation and curtails privilege escalation and code execution paths.
Timely patching also reduces reuse of known techniques against your fleet and cuts alert noise that security operations centers must triage when Android zero-day vulnerabilities are circulating.
Disadvantages: Android’s fragmented ecosystem can delay delivery across OEMs, carriers, and regions. That lag extends the window where Android zero-day vulnerabilities remain exploitable.
Enterprises should apply compensating controls, including strict mobile access policies and network-based detections, until all models are fully updated.
Augment patching with visibility and controls:
Tenable — Exposure management to prioritize remediation.
Auvik — Network monitoring to spot suspicious device traffic.
EasyDMARC — Email authentication to reduce mobile phishing risk.
Optery — Data removal services to limit targeted social engineering.
Conclusion
Google’s December bulletin confirms two exploited issues and a broad set of component fixes. Treat Android zero-day vulnerabilities as a top priority for fleet health.
Patch as updates land, validate coverage, and enforce endpoint and identity controls while rollouts complete. This reduces exposure during staggered delivery.
Continue tracking Google’s advisories and OEM notes for revisions. Effective, well-communicated patching can turn Android zero-day vulnerabilities into a non-event.
Questions Worth Answering
What did Google fix in December 2025?
Two exploited flaws plus numerous vulnerabilities across frameworks, system, kernel, and vendor components received fixes.
Are the exploits active?
Yes. Google reports two issues were exploited in the wild, which elevates urgency.
Which devices should update?
All supported Android devices. Pixels usually get patches first, followed by OEM and carrier rollouts.
How do I update my device?
Go to Settings > Security & privacy > System & updates and install the latest patch.
How can I reduce risk from Android zero-day vulnerabilities during rollout?
Enforce MDM-driven updates, restrict mobile access, monitor traffic, and require phishing-resistant MFA.
Where can I find official details?
See the Android Security Bulletin and the Pixel Update Bulletin.
What role do CVEs play?
CVE identifiers, including items like the CVE-2024-43047 Android vulnerability, guide triage, patch tracking, and communication.
