CVE-2021-47447 Information

Description

In the Linux kernel the following vulnerability has been resolved:

drm/msm/a3xx: fix error handling in a3xx_gpu_init()

These error paths returned 1 on failure instead of a negative error code. This would lead to an Oops in the caller. A second problem is that the check for \if (ret != -ENODATA)\ did not work because et\ was set to 1.
