How to fix?

Upgrade Centos:8 kernel-core to version 0:4.18.0-553.5.1.el8_10 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-core package and not the kernel-core package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

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

i2c: i801: Fix block process call transactions

According to the Intel datasheets, software must reset the block buffer index twice for block process call transactions: once before writing the outgoing data to the buffer, and once again before reading the incoming data from the buffer.

The driver is currently missing the second reset, causing the wrong portion of the block buffer to be read.
