  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nASoC: SOF: ipc3-control: Validate size in snd_sof_update_control\n\nIn snd_sof_update_control(), firmware-provided cdata->num_elems is\nchecked against local_cdata->data->size but never against the actual\nallocation size. If local_cdata->data->size was previously set to an\ninconsistent value, the memcpy could write past the allocated buffer.\n\nAdd a bounds check to ensure num_elems fits within the available space\nin the ipc_control_data allocation before copying.",
