CVE-2025-39930 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ASoC: simple-card-utils: Don't use __free(device_node) at graph_util_parse_dai() commit 419d1918105e ("ASoC: simple-card-utils: use __free(device_node) for device node") uses __free(device_node) for dlc->of_node, but we need to keep it while driver is in use. Don't use __free(device_node) in graph_util_parse_dai().
A vulnerability in the Linux kernel's ASoC (ALSA System on Chip) simple card utilities has been addressed. The issue arose from improper memory management of device node references. Specifically, the function 'graph_util_parse_dai()' incorrectly used '__free(device_node)' to release the device node while it was still needed by the driver. This could potentially lead to use-after-free scenarios or other memory-related issues.
