Refer to the Android and Google Play Protect mitigations section for details on the Android security platform protections and Google Play Protect, which improve the security of the Android platform. This is a summary of the mitigations provided by the Android security platform and service protections such as Google Play Protect.
These capabilities reduce the likelihood that security vulnerabilities could be successfully exploited on Android. In the sections below, we provide details for each of the security vulnerabilities that apply to the patch level.
Vulnerabilities are grouped under the component they affect. When multiple changes relate to a single bug, additional references are linked to numbers following the bug ID. Devices with Android 10 and later may receive security updates as well as Google Play system updates. The most severe vulnerability in this section could enable a local malicious application to bypass user interaction requirements in order to gain access to additional permissions.
The vulnerability in this section could enable a local malicious application to bypass operating system protections that isolate application data from other applications. The most severe vulnerability in this section could enable a local attacker using a specially crafted transmission to gain access to additional permissions.
The most severe vulnerability in this section could result in arbitrary kernel code execution due to a use after free. These vulnerabilities affect MediaTek components and further details are available directly from MediaTek.
The severity assessment of these issues is provided directly by MediaTek. The severity assessment of this issue is provided directly by Widevine DRM. These vulnerabilities affect Qualcomm components and are described in further detail in the appropriate Qualcomm security bulletin or security alert.
The severity assessment of these issues is provided directly by Qualcomm. These vulnerabilities affect Qualcomm closed-source components and are described in further detail in the appropriate Qualcomm security bulletin or security alert.
For some devices on Android 10 or later, the Google Play system update will have a date string that matches the security patch level. Please see this article for more details on how to install security updates. This bulletin has two security patch levels so that Android partners have the flexibility to fix a subset of vulnerabilities that are similar across all Android devices more quickly.
Android partners are encouraged to fix all issues in this bulletin and use the latest security patch level.
Partners are encouraged to bundle the fixes for all issues they are addressing in a single update. Links on Android Authority may earn us a commission.

Instead, they tend to be pretty small in size — around a few hundred megabytes or so. Despite how uneventful they might seem, though, security updates are obviously pretty important.
What this means is that Google develops and maintains the project, but any third party can also volunteer to audit the code, submit suggestions, and modify it for their own use. The latter is precisely why a Samsung phone runs much different software than a Xiaomi or OnePlus device.
In a nutshell, manufacturers build their own features on top of the base provided by Google. Why does this matter? Well, every now and then, security researchers uncover new bugs and vulnerabilities in the Android operating system and submit a disclosure report to Google.
Once the issue is identified, Google develops a patch and merges the updated code with the open-source Android project. Most bugs and security loopholes are pretty minor and will likely not affect the vast majority of individuals immediately.
This is known as responsible disclosure. To that end, multiple patches are typically bunched up into one larger package that reaches your smartphone in the form of a security update. Google notifies device manufacturers of these impending fixes ahead of time so they can all try and release an update simultaneously. Besides the core Android operating system, exploits and vulnerabilities can crop up in several other areas too.
These components communicate with the Android operating system through proprietary code, where similar exploits can be uncovered over time. Some newer smartphones receive updates monthly, while others may only get a new patch every quarter or so. See also : What is stock Android? The former includes fixes for all AOSP-related issues, while the patch level ending in 05 addresses issues associated with third-party components and proprietary code.
In Android 8 and earlier, users had to enable the ability to universally download APKs from outside of the Play Store. In Android 9 , Google required the user to enable this for each individual application. Soon, a new Google Play Store security feature will build upon that and remind users to revoke those permissions afterward. This is a big security improvement, as it helps prevent third-party applications from secretly downloading malicious software.
Google Play Store to offer incognito mode and better device security This Google Play Store security update will give users even more control over their data and help protect them from attacks.
