CVE-2022-20013
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 vow driver, there is a possible memory corruption due to a race condition. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS05837742; Issue ID: ALPS05837742.
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 in the vow driver leads to memory corruption, which can be exploited to achieve local privilege escalation from any user to System-level execution. The vulnerability does not require 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 Android versionCheck the device or system Android version by going to Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if The version is Android 10.0 or Android 11.0 exactly (version matches = 10.0 or = 11.0)
-
Locate the vow driver moduleSearch for the vow driver file in the kernel modules directory or system drivers path. Common locations include /system/lib/modules/ or /vendor/lib/modules/. Use 'find / -name *vow* 2>/dev/null' via ADB shell to locate driver filesAffected if A vow driver file exists on the device, indicating the vulnerable component is present
-
Verify driver is loadedCheck if the vow driver is currently loaded in memory by running 'lsmod | grep vow' or checking /proc/modules via ADB shellAffected if The vow driver module is actively loaded in the kernel
-
Check for patched driver versionIf the vow driver file is found, examine its metadata or version information using 'modinfo <vow_driver_path>' or check the file propertiesAffected if The driver version cannot be verified as patched, or the driver predates patch ALPS05837742
The environment is affected if running Android 10.0 or 11.0 with the vow driver loaded and no evidence of the ALPS05837742 patch applied to the driver

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 patch ALPS05837742 to update the vow driver and remediate the race condition. Verify the driver loads correctly after patching.
