CVE-2024-34733
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn DevmemXIntMapPages of devicemem_server.c, there is a possible arbitrary code execution due to an integer overflow. This could lead to local escalation of privilege in the kernel with no additional execution privileges needed. User interaction is not needed for exploitation.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceInteger overflow in DevmemXIntMapPages function in devicemem_server.c allows a local attacker to achieve arbitrary code execution in kernel context, leading to privilege escalation without requiring additional privileges or user interaction.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm device is running AndroidRun 'getprop ro.build.version.release' or check /system/build.prop for android.os.Build.VERSION.RELEASEAffected if Device is not running Android (the CVE only affects Android)
-
Identify the kernel patch levelRun 'getprop ro.build.version.security.patch' to check the last security patch date. Compare against the patch release date for CVE-2024-34733.Affected if Security patch level is earlier than the month the CVE was patched (unpatched devices are affected)
-
Check if devicemem interface existsLook for /dev/devicemem or check kernel config for CONFIG_DEVICEMEM or search for 'devicemem_server.c' in the kernel source if accessibleAffected if The devicemem interface is present and exposed (the vulnerable code path exists)
-
Verify access to device memory mappingCheck if untrusted apps can access /dev/devicemem or equivalent device memory interface. Use 'ls -la /dev/devicemem' or enumerate /dev for memory mapping devices.Affected if The device memory mapping interface is accessible without elevated privileges (enables local exploitation)
A user is affected if the device runs Android with an unpatched kernel version AND has the devicemem interface accessible for local exploitation.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedApply vendor-supplied kernel patches or update to a patched kernel version. Restrict access to device memory mapping interfaces where possible.
May 2024 Android Security Patch Level or later
- Check the Android Security Bulletin for the month this CVE was addressed (CVE-2024-34733 was fixed in the May 2024 Android Security Bulletin)
- Apply the latest Android system update on your device to receive the kernel security patch
- Verify the security patch level in Settings > About Phone > Build Number matches or exceeds the patch date containing the fix
- For enterprise/organizational devices, ensure Mobile Device Management (MDM) policies enforce automatic security updates
