CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's ASoC (ALSA System on Chip) subsystem, specifically in the handling of topology files where a filename containing "dummy" leads to a memory leak due to improper cleanup of allocated resources. This can result in increased memory consumption over time, potentially impacting system performance and stability. Linux system administrators and developers working with ASoC should prioritize addressing this issue to prevent resource exhaustion in affected environments.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: topology: fix memory leak in snd_sof_load_topology When the topology filename contains "dummy" and tplg_cnt is 0, the function returns -EINVAL directly without freeing the tplg_files allocated by kcalloc() at line 2497. This leaks memory on every such topology load attempt. Fix this by setting ret = -EINVAL and jumping to the out: label, which already handles the kfree(tplg_files) cleanup.
