A flaw was found in the Linux kernel's Sound Open Firmware (SOF) IPC3 control module. This vulnerability, a Time-of-check to Time-of-use (TOCTOU) issue, arises from incorrect size handling during memory copy operations in the bytes_put and bytes_get functions. A local attacker could exploit this to cause data corruption, where valid data might be truncated or stale data copied, potentially resulting in information disclosure or denial of service.
