CVE-2022-49615 Information

Description

In the Linux kernel the following vulnerability has been resolved:

ASoC: rt711-sdca: fix kernel NULL pointer dereference when IO error

The initial settings will be written before the codec probe function. But the rt711->component doesn’t be assigned yet. If IO error happened during initial settings operations it will cause the kernel panic. This patch changed component->dev to slave->dev to fix this issue.
