Overview
About vulnerability
In the Linux kernel, the following vulnerability has been resolved:
ALSA: asihpi: Fix potential OOB array access
ASIHPI driver stores some values in the static array upon a response from the driver, and its index depends on the firmware. We shouldn’t trust it blindly.
This patch adds a sanity check of the array index to fit in the array size.
