Published May 6, 2024
The Android Security Bulletin contains details of security vulnerabilities
affecting Android devices. Security patch levels of
2024-05-05 or later address all of these issues.
To learn how to check a device's security patch level, see
Check and update your Android version
.
Android partners are notified of all issues at least a month before publication. Source code
patches for these issues have been released to the Android Open Source Project (AOSP) repository
and linked from this bulletin. This bulletin also includes links to patches outside of AOSP.
The most severe of these issues is a critical security vulnerability in the System component that could lead to local escalation of privilege with no additional execution privileges needed.
The
severity assessment
is based on the effect that exploiting the vulnerability would possibly have on an affected device, assuming the platform and service mitigations are turned off for development purposes or if successfully bypassed.
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.
Android and Google service mitigations
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.
- Exploitation for many issues on Android is made more difficult by
enhancements in newer versions of the Android platform. We encourage all users
to update to the latest version of Android where possible.
- The Android security team actively monitors for abuse through
Google Play
Protect
and warns users about
Potentially
Harmful Applications
. Google Play Protect is enabled by default on devices
with
Google Mobile
Services
, and is especially important for users who install apps from
outside of Google Play.

Common questions and answers
This section answers common questions that may occur after reading this
bulletin.
1. How do I determine if my device is updated to address these
issues?
To learn how to check a device's security patch level, see
Check and update your Android version
.
- Security patch levels of 2024-05-01 or later address
all issues associated with the 2024-05-01 security patch
level.
- Security patch levels of 2024-05-05 or later address
all issues associated with the 2024-05-05 security patch
level and all previous patch levels.
Device manufacturers that include these updates should set the patch string level to:
- [ro.build.version.security_patch]:[2024-05-01]
- [ro.build.version.security_patch]:[2024-05-05]
For some devices on Android 10 or later, the Google Play system update
will have a date string that matches the 2024-05-01
security patch level.
Please see
this article
for more details on how to install
security updates.
2. Why does this bulletin have two security patch levels?
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.
- Devices that use the 2024-05-01 security patch level
must include all issues associated with that security patch level, as well as
fixes for all issues reported in previous security bulletins.
- Devices that use the security patch level of 2024-05-05
or newer must include all applicable patches in this (and previous) security
bulletins.
Partners are encouraged to bundle the fixes for all issues they are
addressing in a single update.
3. What do the entries in the
Type
column mean?
Entries in the
Type

5. What does an * next to the Android bug ID in the
References
column mean?
Issues that are not publicly available have an * next to the corresponding
reference ID. The update for that issue is generally contained in the latest
binary drivers for Pixel devices available from the
Google Developer site
.
6. Why are security vulnerabilities split between this bulletin and
device/partner security bulletins, such as the
Pixel bulletin?
Security vulnerabilities that are documented in this security bulletin are
required to declare the latest security patch level on Android
devices. Additional security vulnerabilities that are documented in the
device/partner security bulletins are not required for
declaring a security patch level. Android device and chipset manufacturers
may also publish security vulnerability details specific to their products,
such as
Google
,
Huawei
,
LGE
,
Motorola
,
Nokia
, or
Samsung
.
