Description OSIDB Bzimport 2026-05-06 13:12:22 UTC
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.
