CVE-2024-32918
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 · uneditedPermission Bypass allowing attackers to disable HDCP 2.2 encryption by not completing the HDCP Key Exchange initialization steps
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 permission bypass vulnerability in HDCP 2.2 implementations allows attackers to disable encryption by not completing the required Key Exchange initialization steps. The system fails to properly validate that the HDCP authentication handshake has been fully completed before allowing content transmission.

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.
-
Confirm the device runs AndroidCheck the device's OS by going to Settings > About Phone, or run 'getprop ro.build.version.release' via ADB shell to verify the operating system is AndroidAffected if The device runs any version of Android (all versions are affected)
-
Verify if HDCP output protection is enabledCheck Android display/enterprise security settings, or inspect system property 'persist.hdcp.enable' via 'getprop persist.hdcp.enable' command; also check for HDCP-related settings in Settings > Security > HDCP or equivalentAffected if HDCP is enabled on the device, as the vulnerability affects HDCP 2.2 implementations when active
-
Check for external display connections using HDCPInspect /sys/class/drm or /d/dri directories for connected displays, or check logs via 'logcat -d | grep -i hdcp' for any HDCP authentication eventsAffected if The device has an active external display connection using HDCP protection
-
Review HDCP authentication logs for validation failuresRun 'logcat -d | grep -i "hdcp\|key.exchange\|authentication"' to examine system logs for HDCP handshake completion statusAffected if Logs show HDCP connections proceeding without proper Key Exchange initialization completion
A user is affected if they run Android with HDCP 2.2 enabled and external display output capability, as the vulnerability allows content transmission without validated handshake completion.

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 strict validation requiring confirmed completion of HDCP Key Exchange initialization before enabling content output. Add integrity checks to ensure the full authentication handshake sequence is executed.
