CVE-2025-71286

Summary

In the Linux kernel, the following vulnerability has been resolved:

ASoC: SOF: ipc4-topology: Correct the allocation size for bytes controls

The size of the data behind of scontrol->ipc_control_data for bytes controls is: [1] sizeof(struct sof_ipc4_control_data) + // kernel only struct [2] sizeof(struct sof_abi_hdr)) + payload

The max_size specifies the size of [2] and it is coming from topology.

Change the function to take this into account and allocate adequate amount of memory behind scontrol->ipc_control_data.

With the change we will allocate [1] amount more memory to be able to hold the full size of data.
