I have no knowledge of how the integrity of the Linux kernel is protected. So a small bit of background context would be nice. The article says this is a patch set. I assume this gets reviewed before it’s allowed into the kernel. I’m assuming the exploits were found before the patch was excepted. I can see a frustration in having to review really bad code.

No, this code wasn't proposed for inclusion in the Linux kernel. To do that, someone would have to send an email to the Linux kernel mailing list that says what the changes are for, who wrote them, etc. This is probably just something that Huawei wrote for their own custom kernel for their phones or something.
