CVE-2026-72261

ASoC: SOF: ipc3-control: Validate size in snd_sof_update_control

State: Published
Severity: 7.8 High

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.
