# CVE-2021-47446

> 7.8 HIGH

## Beschreibung

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 "ret" is set to 1.
