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.

A flaw was found in the Linux kernel's Sound Open Firmware (SOF) subsystem, specifically within the `ipc3-control` component. This vulnerability occurs in the `snd_sof_update_control()` function where the size of firmware-provided data is not properly validated against the allocated buffer size. An attacker could exploit this by providing a malformed size, leading to a buffer overflow. This could result in memory corruption, potentially causing system instability or a denial of service.
