CVE-2024-34725
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 DevmemIntUnexportCtx of devicemem_server.c, there is a possible arbitrary code execution due to a race condition. 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 confidenceA race condition vulnerability exists in the DevmemIntUnexportCtx function in devicemem_server.c that could allow a local attacker to achieve arbitrary code execution in kernel context, resulting in 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.
-
Identify if the device runs AndroidCheck the OS type using 'getprop ro.build.type' or 'cat /proc/version' to see if Linux kernel is running on AndroidAffected if The device is running Google Android as the operating system
-
Check the kernel versionRun 'uname -r' or 'cat /proc/version' to obtain the kernel version stringAffected if The kernel version is older than the patched version for CVE-2024-34725 (compare against the patched kernel version for your Android release)
-
Verify devicemem module is presentCheck for the devicemem kernel module or device node using 'ls -la /dev/devicemem' or 'lsmod | grep devicemem' if the module is loadableAffected if The devicemem functionality is present and the kernel lacks the CVE-2024-34725 patch
-
Confirm the race condition fix is absentInspect the kernel symbols or binary for the DevmemIntUnexportCtx function presence using 'grep DevmemIntUnexportCtx /proc/kallsyms' or examine the devicemem_server.c source if accessibleAffected if The function exists without proper synchronization fixes applied (the patched version adds mutex/lock protection)
-
Check for available security updatesVerify the Android security patch level using 'getprop ro.build.version.security_patch'Affected if The security patch level is earlier than the month the CVE-2024-34725 patch was released
A user is affected if the Android device runs an unpatched kernel lacking the CVE-2024-34725 fix in the devicemem driver, particularly when the devicemem functionality is accessible.

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.
From vendor dataApply the kernel patch for CVE-2024-34725 which addresses the race condition through proper synchronization in the device memory unexport handling code.
