CVE-2020-12485
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 · uneditedThe frame touch module does not make validity judgments on parameter lengths when processing specific parameters,which caused out of the boundary when memory access.The vulnerability eventually leads to a local DOS on the device.
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 confidenceThe frame touch module lacks bounds validation on parameter lengths when processing specific parameters, leading to out-of-bounds memory access. This memory corruption vulnerability results in a local denial of service on the affected device.

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 Vivo Frame Touch Module is presentCheck system modules or driver list for 'frame touch' or 'touch' module. On Linux: lsmod | grep -i touch. On Windows: Check Device Manager or driver inventory for touch-related drivers.Affected if The frame touch module is not installed on the system.
-
Determine the frame touch module versionRun version check on the touch module. On Linux: modinfo <touch_module_name> or cat /sys/module/<touch_module_name>/version. On Windows: Right-click the driver in Device Manager > Properties > Driver version. Compare against version 10.Affected if The installed version is exactly 10.
-
Verify the parameter processing feature is enabledCheck module parameters or configuration for the frame touch module. On Linux: cat /sys/module/<touch_module_name>/parameters/. On Windows: Check registry under HKLM\SYSTEM\CurrentControlSet\Services\<touch_service>. Look for any parameter-related settings.Affected if The parameter processing functionality is actively enabled.
-
Inspect access to vulnerable parameter inputsReview how the touch module receives input parameters. Check configuration files, API endpoints, or ioctl calls that pass parameters to the frame touch module. Determine if applications can supply parameter lengths to the module.Affected if User-space applications or kernel parameters can directly influence the module's parameter processing without validation.
A system is affected if it runs Vivo Frame Touch Module version 10 with the parameter processing feature enabled and accessible to supply parameter lengths.

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 dataImplement proper parameter length validation and bounds checking in the frame touch module before memory access operations to prevent out-of-bounds writes.
