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
