CVE-2024-29739
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 tmu_get_temp_lut of tmu.c, there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure 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 missing bounds check in the tmu_get_temp_lut function of the tmu.c kernel driver allows an out of bounds read when accessing a lookup table (LUT). This could expose sensitive kernel memory contents to a local attacker without requiring any special 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 Google Android is the running platformCheck /system/build.prop or run 'getprop ro.build.fingerprint' to verify the OS is Google AndroidAffected if The device is running any version of Google Android (all versions are affected)
-
Identify if tmu kernel driver is presentCheck for tmu.ko in /system/lib/modules/ or /vendor/lib/modules/, or check /proc/modules for 'tmu' module loadedAffected if The tmu (Thermal Management Unit) driver is loaded or present on the device
-
Verify vulnerable function exists in kernelUse 'grep -l tmu_get_temp_lut /proc/kallsyms' or examine the tmu driver binary for the tmu_get_temp_lut function symbolAffected if The tmu_get_temp_lut function is exported or present in the loaded kernel/driver
-
Check for untrusted device accessVerify if any untrusted applications or processes can access thermal management interfaces (check /sys/class/thermal or device nodes used by tmu driver for read access)Affected if Thermal management device nodes or sysfs interfaces are readable by local attackers without special privileges
If the device runs Google Android and contains the tmu kernel driver with the tmu_get_temp_lut function, the out-of-bounds read vulnerability is present and could expose kernel memory to local unprivileged attackers.

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 dataAdd proper bounds checking before accessing the temperature lookup table index in tmu_get_temp_lut to ensure the index is within valid bounds before dereferencing.
