CVE-2022-32596
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 widevine, there is a possible out of bounds write due to an incorrect bounds check. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS07446213; Issue ID: ALPS07446213.
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 confidenceThis is an out-of-bounds write vulnerability in Google's Widevine DRM library caused by an incorrect bounds check. It allows a local attacker with System-level execution privileges to escalate privileges, potentially achieving code execution at a higher privilege level. No user interaction is required for exploitation.

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 versionRun 'adb shell getprop ro.build.version.release' or check Settings > About Phone > Android version. Confirm it is exactly 10.0, 11.0, or 12.0.Affected if Android version is 10.0, 11.0, or 12.0 and Widevine DRM library is present on the device.
-
Locate Widevine DRM library filesRun 'adb shell find /system -name "*widevine*" -o -name "*wv*" 2>/dev/null' to find Widevine library files typically stored in /system/lib/mediadrm or /vendor/lib/mediadrm directories.Affected if Widevine library files exist on the system.
-
Check Widevine DRM plugin versionNavigate to Settings > Apps > Google Play Services > DRM Info, or run 'adb shell dumpsys media.drm' to query the Widevine plugin version string.Affected if The Widevine DRM version is older than the fixed version provided in the vendor patch (ALPS07446213). Compare your version against the affected release timeline.
-
Verify Widevine DRM service is runningRun 'adb shell dumpsys media.drm' or 'adb shell ps -A | grep -i drm' to confirm the DRM service is active and Widevine is loaded.Affected if Widevine DRM is actively loaded and the Android version falls within the affected versions (10.0, 11.0, 12.0).
If the device runs Android 10.0, 11.0, or 12.0 and has Widevine DRM library present with a version predating the patch, the environment is affected by CVE-2022-32596.

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 patch (ALPS07446213) by updating Widevine through Google Chrome, Chrome OS, or Android platform updates that incorporate the fixed Widevine library version.
