Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
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 "ret" was set to 1.
