Description
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: ipc3-control: Validate size in snd_sof_update_control
In snd_sof_update_control(), firmware-provided cdata->num_elems is
checked against local_cdata->data->size but never against the actual
allocation size. If local_cdata->data->size was previously set to an
inconsistent value, the memcpy could write past the allocated buffer.
Add a bounds check to ensure num_elems fits within the available space
in the ipc_control_data allocation before copying.
