CVE-2022-39120
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 sensor driver, there is a possible out of bounds write due to a missing bounds check. This could lead to local denial of service in kernel.
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 · low confidenceIn a sensor driver within the Linux kernel, an out-of-bounds write vulnerability exists due to a missing bounds check. This allows a local attacker to trigger the vulnerability, potentially causing a denial of service through kernel crash or instability.
Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

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.
-
Check Android OS versionNavigate to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if The reported version equals 10.0, 11.0, or 12.0 exactly
-
Identify kernel versionRun 'uname -r' in ADB shell or check /proc/versionAffected if Kernel version corresponds to an Android 10.0, 11.0, or 12.0 release for your device model
-
List loaded sensor kernel modulesRun 'lsmod' or check /proc/modules in ADB shell to enumerate currently loaded kernel modules related to sensorsAffected if Any sensor driver module is currently loaded and active in the kernel
-
Identify sensor driver presence in kernelCheck /sys/class/sensors/ directory for available sensor entries, or review kernel config for sensor driver compilation statusAffected if Sensor driver support is compiled into or loaded by the running kernel
-
Verify sensor driver is actively usedQuery sensor data via sensorservice or check /dev/ for sensor device nodes, or monitor sensor input via geteventAffected if Any sensor is actively consuming data from the driver
Your device is likely affected if it runs Android 10.0, 11.0, or 12.0 and has any sensor driver module loaded, since the vulnerability exists in the sensor driver code path for these versions.
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.
From vendor dataApply the vendor-supplied kernel security patch which adds proper bounds validation to the sensor driver. Alternatively, if no patch is available, disable or blacklist the affected sensor driver until a fix is released.
