CVE-2024-27226
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_config_gov_params of , there is a possible out of bounds write due to a missing bounds check. This could lead to local escalation of privilege 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_config_gov_params function allows an out-of-bounds write, which can be exploited for local privilege escalation without requiring user interaction or additional execution privileges. The vulnerability stems from insufficient input validation when configuring thermal management government parameters.

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 Android version is 13.0Run 'getprop ro.build.version.release' in a shell or check Settings > About Phone > Android versionAffected if The version shown is exactly 13.0 (not 12.x, 14.x, or other versions)
-
Identify the kernel versionRun 'uname -a' to display kernel version informationAffected if Kernel is from the Android 13.0 release cycle (specific kernel version varies by device OEM)
-
Check if thermal management interface existsInspect /sys/class/thermal/ for thermal zone directories, or check for tmu (thermal management unit) sysfs entries under /sys/devices/virtual/thermal/Affected if Thermal management subsystem is accessible and the device uses tmu-based thermal governance
-
Verify tmu_config_gov_params function presenceCheck /proc/kallsyms or decompile the kernel image to search for the symbol 'tmu_config_gov_params'Affected if The function exists in the kernel without bounds checking implemented
Device is affected if running Android 13.0 with a kernel containing the tmu_config_gov_params function lacking proper bounds validation in the thermal management code path.

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 a patch that adds proper bounds checking before writing to the tmu_config_gov_params function parameters to prevent out-of-bounds memory access. This is typically a kernel-level fix requiring code review and testing.
