Published June 3, 2024

The Android Security Bulletin contains details of security
vulnerabilities affecting Android devices. Security patch levels
of 2024-06-05 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 will be
released to the Android Open Source Project (AOSP) repository in
the next 48 hours. We will revise this bulletin with the AOSP
links when they are available.

The most severe of these issues is a high 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.

2024-06-01 security patch level vulnerability details

In the sections below, we provide details for each of the
security vulnerabilities that apply to the 2024-06-01 patch
level. Vulnerabilities are grouped under the component they
affect. Issues are described in the tables below and include CVE
ID, associated references, type of
vulnerability, severity, and updated AOSP versions (where
applicable). When available, we link the public change that
addressed the issue to the bug ID, like the AOSP change list.
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.

Framework

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 2024-06-01 or later address all
  issues associated with the 2024-06-01 security patch
  level.
• Security patch levels of 2024-06-05 or later address all
  issues associated with the 2024-06-05 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]:[2024-06-01]
• [ro.build.version.security_patch]:[2024-06-05]

For some devices on Android 10 or later, the Google Play
system update will have a date string that matches the 2024-06-01
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 2024-06-01 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 2024-06-05 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 column of the vulnerability
details table reference the classification of the security
vulnerability.

4. What do the entries in the References
column mean?

Entries under the References column of the
vulnerability details table may contain a prefix identifying the
organization to which the reference value belongs.

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.
