AI-suggested
A fix has been implemented in the Linux kernel to skip the HDCP configuration routine when the transition state lacks a valid dm_stream_ctx. Users should update to a fixed kernel version to remediate this vulnerability.
Description
A vulnerability in the Linux kernel's AMD display driver related to HDCP configuration has been resolved. The issue occurs when the transition state lacks a valid dm_stream_ctx, causing the HDCP configuration routine to run improperly. The fix ensures the routine only executes when a valid stream context is present.
