CVE-2022-20030
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 out of bounds write due to a stack-based buffer overflow. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS05837793; Issue ID: ALPS05837793.
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 stack-based buffer overflow in the vow driver allows an out-of-bounds write beyond the stack-allocated buffer boundary. This enables local privilege escalation from a normal application context to System-level execution without user interaction, as the driver runs with elevated privileges.

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 versionOpen Settings > About Phone > Android version, or run 'getprop ro.build.version.release' via ADB shellAffected if Version is 10.0, 11.0, or 12.0 exactly
-
Identify vow driver presenceCheck for vow driver in kernel modules or device driver directory; run 'ls /dev/vow*' or search for 'vow' in /proc/modules via ADB shell with root accessAffected if The vow driver is loaded or present on the device
-
Verify security patch levelRun 'getprop ro.build.version.security_patch' via ADB shell to check the installed security patch dateAffected if Security patch level is earlier than the vendor fix ALPS05837793, or patch date is not visible/available
Device is affected if running Android 10.0, 11.0, or 12.0 and the vow driver is present without the vendor patch ALPS05837793 applied.

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.
dbcve · scopedApply vendor patch ALPS05837793 or update to a device/firmware version containing the fix. As this is a driver-level vulnerability, users must obtain an OEM-provided system update.
Android 12 with July 2022 Security Patch Level or later (or the latest available Android version with corresponding security patches from your OEM)
- 1. Check current Android security patch level on the device (Settings > Security > Security patch level)
- 2. Verify the device has received the July 2022 Android Security Bulletin patch or later
- 3. If not yet patched, check for system updates from the device OEM and apply the latest available update
- 4. Confirm the patch ALPS05837793 has been applied by verifying the security patch level is July 2022 or newer
- 5. For enterprise-managed devices, ensure MDM policies enforce minimum OS version and security patch levels
