CVE-2025-71286

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ASoC: SOF: ipc4-topology: Correct the allocation size for bytes controls<br /> <br /> The size of the data behind of scontrol-&gt;ipc_control_data for bytes<br /> controls is:<br /> [1] sizeof(struct sof_ipc4_control_data) + // kernel only struct<br /> [2] sizeof(struct sof_abi_hdr)) + payload<br /> <br /> The max_size specifies the size of [2] and it is coming from topology.<br /> <br /> Change the function to take this into account and allocate adequate amount<br /> of memory behind scontrol-&gt;ipc_control_data.<br /> <br /> With the change we will allocate [1] amount more memory to be able to hold<br /> the full size of data.
