CVE-2022-49247

Estado: AnalizadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

media: stk1160: If start stream fails, return buffers with VB2_BUF_STATE_QUEUED

If the callback 'start_streaming' fails, then all queued buffers in the driver should be returned with state 'VB2_BUF_STATE_QUEUED'. Currently, they are returned with 'VB2_BUF_STATE_ERROR' which is wrong. Fix this. This also fixes the warning:
