AI-suggested

A patch is available and should be applied to affected Linux kernel versions to resolve the memory leak. Users should update to the fixed kernel versions as provided by their distribution vendors. No additional mitigation actions are required beyond applying the official fix.

Description

A memory leak vulnerability in the Linux kernel's ASoC SOF topology loading function was fixed. The issue occurs when the topology filename contains "dummy" and tplg_cnt is 0, causing the function to return early without freeing allocated memory. This leads to a memory leak on each such topology load attempt. The fix ensures proper cleanup by jumping to a label that frees allocated resources.
