CVE-2024-53051

Summary

CVE-2024-53051 is a recently identified vulnerability in the Linux kernel's drm/i915/hdcp module. The issue arises during hotplug scenarios or suspend/resume scenarios when the encoder is not always initialized prior to the call to intel_hdcp_get_capability. This can result in a kernel null pointer dereference, potentially leading to system instability or even a complete system crash. The vulnerability has been resolved by adding a check to ensure the encoder is initialized before making the call to intel_hdcp_get_capability.
