A flaw was found in the ASoC Sound Open Firmware (SOF) ipc4-control component of the Linux kernel. This vulnerability arises from insufficient validation of the MODULE_NOTIFICATION payload length when handling control updates. An attacker could potentially exploit this by providing a malformed notification, which may lead to unexpected system behavior or a denial of service.
