Answer in brief
CVE-2021-47447 records a High severity (CVSS 7.8) vulnerability in drm/msm/a3xx: fix error handling in a3xx_gpu_init(). The current sources do not mark it as known exploited. The current feed maps Linux/Linux (generic), Linux/Linux (generic). Check affected ranges and fixed versions before updating.
Analysis pending evidence review
HOL Guard separates source facts from reviewed analysis. See the methodology.
CVSS is 7.8. The current sources do not mark it as known exploited. Treat this as a source-backed prioritization signal, not a statement about your environment.

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.
