Android Patchday & exploited vulnerabilities: What businesses need to know now
In the course of the monthly Android Patchday in 2025, critical vulnerabilities in Google’s mobile operating system were once again revealed – some of which have already been actively exploited. For companies that use Android-based devices in their daily operations or manage them via MDM solutions, these developments mean an immediate need for action.
In this article, we show which security gaps have been closed with the latest Android patchday, what risks exist if devices are not up to date and how companies can effectively secure their device fleets. You will also find out why regular device replacement via professional smartphone rental or tablet rental makes particular sense.
What is the Android Patchday?
Android Patchday is a monthly event on which Google releases security updates for the Android operating system. Vulnerabilities are identified, assessed and fixed via security updates. These updates affect both the Android Open Source Project (AOSP) and device manufacturers, who in turn adapt and deliver the patches to their own devices.
Since the beginning of 2025, Google has significantly tightened its focus on zero-day vulnerabilities. In January and February 2025, a total of over 40 vulnerabilities were closed – including several exploits classified as “critical”.
These vulnerabilities became known during Android Patchday 2025
| Patchday | Number of vulnerabilities | Critical vulnerabilities | Already exploited | Affected components |
|---|---|---|---|---|
| January 2025 | 23 | 5 | Yes | Kernel, System, Media Framework |
| February 2025 | 19 | 4 | Partial | Bluetooth, Graphics, Framework |
| March 2025 | 27 | 6 | Yes | System, GPU driver, wireless |
A vulnerability in the Media Framework was particularly critical in March 2025, allowing attackers to execute code with system rights via manipulated media files. According to security researchers, this type of vulnerability has already been observed in targeted attacks.
Implications for companies and institutional users
The use of unpatched Android devices poses a significant risk – especially if these devices contain business-critical data or access to sensitive systems. The most common threats from exploited vulnerabilities are:
- Data theft through remote code execution
- Sabotage of active processes through system interventions
- Extension of user rights (privilege escalation)
- Abuse of location or microphone access for espionage
A central problem: many companies use Android devices with an outdated Android version that no longer receives security patches. Security updates are often missing, especially for devices purchased after the two-year usage period. In such cases, the rental of up-to-date smartphones is recommended to ensure the long-term protection of your own data.
Why regular updates alone are often not enough
Even if companies pursue internal security guidelines and MDM strategies, they can still have problems accessing the latest patches for devices from certain manufacturers. The reason for this is the fragmentation in the Android ecosystem: manufacturers and mobile network providers are responsible for the delivery of updates – which can lead to delays or even the absence of important updates.
What’s more, devices purchased as leasing or rental models often receive updates faster and more regularly – as rental providers like us at [company name] offer central patch management and proactively monitor the device fleets used. Models such as the Samsung Galaxy S25 or the powerful Galaxy S25 Ultra in particular are always up-to-date as part of modern rental solutions and offer long-term protection.
Recommended measures for companies
To secure their infrastructure, companies should consider the following security concept:
- Automate patch management: Use an MDM solution to centralize update processes.
- Check device fitness: Identify Android devices that are no longer receiving updates – and replace them promptly.
- Rent devices instead of buying them: A professional rental service provides you with devices with guaranteed update support & replacement service. Especially in the tablet sector, powerful models such as the Samsung Galaxy Tab S10 Plus offer the greatest possible security and flexibility for rental. Rental of the latest business smartphones is also recommended for smartphone solutions.
- Tighten security guidelines: Specify that devices older than 24 months are no longer permitted in the business access scenario.
High flexibility with maximum security is particularly important in mobile fields of application such as logistics, field service or events. Here it pays to rely on tested devices with ongoing patches – as with tablet rental for companies with daily security updates.
Android Patchday as a trigger for evaluating your device strategy
Whenever new security-related topics arise in the Android cosmos, this is also an opportunity for IT managers to reflect on their own fleet strategy. How well are your devices secured? Which devices are running an outdated OS and when is it worth taking them out of service?

- Regular software maintenance and patch management
- Device replacement in the event of incompatibilities or outdated firmware
- Secure pre-configuration in accordance with GDPR requirements
- Device pool for short-term requirements, e.g. events or test phases

FAQ – Frequently asked questions about Android Patchday and device management
What happens if I don’t update Android devices regularly?
Unpatched devices pose a high security risk. Attackers can exploit known vulnerabilities to execute malicious code or steal data. This is particularly critical in business contexts with sensitive customer data. In order to be protected at all times, it is advisable to use modern devices such as the Samsung Galaxy S25 as part of a professional rental.
How do I find out if my Android device is affected?
Device manufacturers regularly publish security instructions and support documentation. With an MDM system, you can centrally check which devices are up to date. The integration of current rental tablets with guaranteed vendor support is even easier.
What do I do with old devices without update support?
If devices no longer receive updates, they should either be replaced or used with severely restricted user profiles. A professional device rental company offers quick solutions by providing a replacement service or upgrades to the latest rental smartphones or powerful Android tablets.
Are there special Android versions with a longer update period?
Yes, Android Enterprise Recommended devices or models with Android One usually offer a longer update guarantee. Get advice before you invest and discover the latest devices such as the Samsung Galaxy S25 Ultra for rental, which offer security and a guarantee for the future.
Conclusion: Security through professional management and up-to-date end devices
Every month, the Android Patchday shows once again that using mobile devices without a well thought-out security concept is a risk. Especially in the year 2025, when several zero-day exploits have been uncovered, it is essential to react quickly.
