Aug 15 ENRICHED — CVE-2022-49518 (Linux). Received CVSS 7.1 and CPE data from NVD.
Description
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: ipc3-topology: Correct get_control_data for non bytes payload
It is possible to craft a topology where sof_get_control_data() would do
out of bounds access because it expects that it is only called when the
payload is bytes type.
Confusingly it also handles other types of controls, but the payload
parsing implementation is only valid for bytes.
Fix the code to count the non bytes controls and instead of storing a
pointer to sof_abi_hdr in sof_widget_data (which is only valid for bytes),
store the pointer to the data itself and add a new member to save the size
of the data.
In case of non bytes controls we store the pointer to the chanv itself,
which is just an array of values at the end.
In case of bytes control, drop the wrong cdata->data (wdata[i].pdata) check
against NULL since it is incorrect and invalid in this context.
The data is pointing to the end of cdata struct, so it should never be
null.
