Description OSIDB Bzimport 2025-02-26 03:12:36 UTC 
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.
