NVD Description

Note: Versions mentioned in the description apply only to the upstream rv package and not the rv package as distributed by Centos. See How to fix? for Centos:9 relevant fixed versions and status.

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

dmaengine: qcom-adm: fix wrong calling convention for prep_slave_sg

The calling convention for pre_slave_sg is to return NULL on error and provide an error log to the system. Qcom-adm instead provide error pointer when an error occur. This indirectly cause kernel panic for example for the nandc driver that checks only if the pointer returned by device_prep_slave_sg is not NULL. Returning an error pointer makes nandc think the device_prep_slave_sg function correctly completed and makes the kernel panics later in the code.

While nandc is the one that makes the kernel crash, it was pointed out that the real problem is qcom-adm not following calling convention for that function.

To fix this, drop returning error pointer and return NULL with an error log.
