CVE-2022-49615

Estado: ModificadaMedia (5.5)—

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.
