Android 13 (Tiramisu): Known Issues & Vulnerabilities

 

📌 Android 13 (Tiramisu): Known Issues & Vulnerabilities

🛡️ Official Security Vulnerabilities and Patches

Android’s security model relies heavily on monthly security updates from Google. These updates include fixes for vulnerabilities in core components such as the Android Framework, System components, and the Linux kernel. Android 13 devices that have current security patches are protected against these issues. (Android Open Source Project)

👾 High-Severity Vulnerabilities & Zero-Day Exploits (2025)

December 2025 Security Update (Android 13 +)
In late 2025, Google released a major update addressing 107 vulnerabilities affecting Android versions including Android 13. Notable high-severity issues include: (Tom's Guide)

  • CVE-2025-48633 — Information Disclosure: affects the Android Framework; could expose sensitive memory data and is confirmed to be under limited targeted exploitation. (SOCRadar® Cyber Intelligence Inc.)

  • CVE-2025-48572 — Elevation of Privilege: allows a local attacker (e.g., via a malicious app) to gain higher system privileges. (SOCRadar® Cyber Intelligence Inc.)

  • CVE-2025-48631 — Denial of Service (DoS): enables crashing of key system components without needing elevated permissions. (TheCyberThrone)

Security advisories from Tom’s Guide and Malwarebytes confirm that these patches are applied to Android 13 devices once vendors roll them out, and users are strongly urged to install them quickly. (Tom's Guide)

Prior 2025 Patches
Earlier bulletins (e.g., April 2025) resolved additional serious bugs including elevation of privilege issues in the System component that could be exploited without user interaction. (SecurityWeek)

⚠️ Government Cybersecurity Advisories

CERT-In (India) issued warnings citing multiple vulnerabilities impacting Android versions up to Android 13, which could allow:

  • unauthorized access to sensitive data

  • privilege escalation

  • denial of service

These alerts emphasise the importance of keeping Android security patches up to date. (India Today)

Similarly, other national cybersecurity bodies (e.g., in UAE) have reiterated ongoing risks from unpatched Android vulnerabilities, focusing on exploits that affect older components of the OS.

🔧 Non-Security Bugs & User-Reported Issues

While official security bulletins focus on security flaws, broad user feedback and beta test discussions show a variety of functional bugs and usability issues in Android 13’s lifecycle — especially early on:

🧪 Beta & Early-Release Bugs

During development and early deployment, users reported:

  • UI glitches: icons or widgets disappearing after update. (Reddit)

  • Connectivity problems: Wi-Fi or mobile signal dropouts on some devices. (Reddit)

  • Touchless payment/NFC issues on some builds. (Reddit)

  • Screenshot freezes: screenshots causing apps to hang. (Reddit)

These were mostly beta-specific or early OTA problems and generally resolved before stable releases. (Reddit)

📱 Early User Reports After Stable Release

Independent forum users (e.g., on Reddit) noted additional practical issues on devices running Android 13:

  • Battery drain and thermal issues on certain Pixel models. (Reddit)

  • Wireless charging reliability problems after updating. (Reddit)

  • Voice assistant activation glitches. (Reddit)

These device-specific reports reflect the complex interaction between Android versions and OEM-specific drivers or firmware.

🧠 Why These Issues Matter

Security Vulnerabilities
Unpatched security flaws like zero-days or privilege escalation bugs can compromise user data, device integrity, and network security. They are especially relevant for sensitive deployments in enterprise or government contexts. (SOCRadar® Cyber Intelligence Inc.)

Functional Bugs
Even non-security bugs can affect daily usability, leading to crashes, connectivity issues, or degraded performance until updates are applied or fixes are rolled out by device manufacturers.

📍 How to Stay Protected

1. Always Update:
Install the latest security patch level your device offers (check Settings → System → System updates). (Android Open Source Project)

2. Enable Play System Updates:
Google Play system updates deliver additional security patches outside full OS upgrades.

3. Install Only Trusted Apps:
Installing apps only from the Google Play Store reduces exposure to malicious software.

4. Monitor Security Advisories:
Cybersecurity alerts from CERT-In or equivalent bodies help you track critical vulnerabilities quickly.
