Description OSIDB Bzimport 2025-06-18 12:12:06 UTC 
In the Linux kernel, the following vulnerability has been resolved:

ASoC: SOF: ipc3-topology: Prevent double freeing of ipc_control_data via load_bytes

We have sanity checks for byte controls and if any of the fail the locally
allocated scontrol->ipc_control_data is freed up, but not set to NULL.

On a rollback path of the error the higher level code will also try to free
the scontrol->ipc_control_data which will eventually going to lead to
memory corruption as double freeing memory is not a good thing.
