CVE-2021-47446 Information

Description

In the Linux kernel the following vulnerability has been resolved:

drm/msm/a4xx: fix error handling in a4xx_gpu_init()

This code returns 1 on error instead of a negative error. It leads to an Oops in the caller. A second problem is that the check for \if (ret != -ENODATA)\ cannot be true because et\ is set to 1.
