What is CVE-2024-29748?

There is a possible way to bypass due to a logic error in the code. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.

A successful exploit gives the attacker the impact described in the vendor advisory. The fix is to install the patched build from Google listed in the table above and confirm the running version after the upgrade.

Am I affected?

Check your installed version of Google Android against the Affected row above. If your build sits within any of those ranges, treat the system as vulnerable until patched.

If you do not have the version handy, pull it the same way you usually would for Android: the management console's About page, the CLI's version command, or the package manager record for the installed binary. The vendor advisory linked in the references section is the authoritative source.

How to fix CVE-2024-29748

  1. Read the vendor advisory at https://source.android.com/security/bulletin/pixel/2024-04-01 for the build matrix that matches your installation.
  2. Identify the patched build for your major version from the advisory's downloads section.
  3. Back up configuration before upgrading (export running config, snapshot the VM, or take a database dump as appropriate for your platform).
  4. Apply the patched build using the vendor's documented upgrade path (in-place upgrade, package update, or replacement image).
  5. Restart the service so the new code is loaded; verify the running version reports the patched build number.

Apply the Android security bulletin update


# Confirm the device's current Android security patch level
adb shell getprop ro.build.version.security_patch

# Required patch level is listed in the vendor advisory: https://source.android.com/security/bulletin/pixel/2024-04-01
# Install the OTA from Settings -> System -> System update, or sideload
# the factory image referenced in the advisory.
adb reboot bootloader
fastboot -w update image-<device>-<build>.zip


# Confirm Android Enterprise managed devices have the security patch (Intune example)
Connect-MgGraph -Scopes Device.Read.All
Get-MgDeviceManagementManagedDevice -Filter "operatingSystem eq 'Android'" |
  Select-Object DeviceName, OSVersion, AndroidSecurityPatchLevel

Verify the fix landed


# 1. Confirm the running version matches the fixed-in version from the advisory:
#    https://source.android.com/security/bulletin/pixel/2024-04-01
#    Use the platform-specific version probe above.

# 2. Re-scan with your vulnerability scanner (Nessus, Qualys, Tenable, OpenVAS).
#    The scanner should no longer flag CVE-2024-29748 on the patched target.

# 3. Inspect recent service / kernel logs for crash loops or rollback events.
journalctl -u <service> --since "10 minutes ago"
dmesg --since "10 minutes ago"

If you can't patch immediately

Check the vendor advisory's "Workarounds" section. If the advisory lists no official workaround, patching is the only remediation. Compensating controls that reduce attack surface in the meantime: restrict network access to the management interface to a small admin allowlist, disable the affected feature if it is not in use, and monitor the relevant logs for the exploitation patterns referenced in the advisory.

How to verify the fix worked

  1. Confirm the running version matches the patched build from the vendor advisory.
  2. Re-run your vulnerability scanner; the CVE should clear.
  3. Review logs from before the patch for the exploitation signatures described in the advisory, and treat any matches as a possible compromise (rotate credentials, isolate the host, full IR).

Frequently asked questions

Other vulnerabilities in the same area that are worth patching alongside this one:

Is CVE-2024-29748 being exploited right now?

Yes. It is listed in the CISA Known Exploited Vulnerabilities catalog (added 2024-04-04), which means CISA has evidence of active exploitation.

What is the CVSS score for CVE-2024-29748?

CVSS 0.0. Use this with your own asset exposure to set patching priority (internet-exposed systems first).

Do I need to take the system offline to patch?

It depends on the platform. Many appliances support hitless upgrade in HA pairs (upgrade standby, fail over, upgrade primary). Servers and applications usually need a service restart. Plan a maintenance window if HA is not available.

What if my version is not listed as affected?

Cross-check against the vendor advisory linked below. The CVE record reflects the vendor's official affected-products list at publication time; later-discovered variants are added through the same advisory or a follow-up CVE.
