CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's handling of DisplayPort alternate mode in the AMD display driver, where a reference to a previous sink is not properly released during a timeout scenario. This oversight could lead to memory leaks, potentially impacting system performance and stability. Organizations using Linux systems with AMD graphics should prioritize addressing this issue to maintain optimal resource management and prevent degradation of service.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: detect_link_and_local_sink: DP alt mode timeout path leaks prev_sink reference prev_sink is unconditionally retained via dc_sink_retain at function entry, but the DP alt mode timeout path inside SIGNAL_TYPE_DISPLAY_PORT returns false without releasing prev_sink. All other return paths in the function correctly call dc_sink_release(prev_sink), making this the only missing cleanup. (cherry picked from commit 45510cf662dcf46b5d8926d454f338809f107b9d)
