I wouldn't attribute it to malice - just engineers without the right time and/or training.
My guess that it comes from a person who is posting a patch for the first time to the mailing list.
attributing this patch to Huawei doesn't make sense, and if they really did want to introduce a backdoor I'll only assume that they would have prepared much better patches.
these kind of one time submissions are most likely to be ignored in the mailing list..
I think it only got attention because someone saw Huawei in the headline.
It's good GRS tries to raise awareness, but this could very well be an WIP or just some intern fooling around with Linux.
Never attribute to malice...stupidity. However, I'm guessing since it is Huawei, it will always (deservedly?) be suspect as malice first?
IIRC the 2019 report from HCSEC outlined the same bugs had yet to be fixed. I think Huawei doesn't want to fix bugs in products they aren't currently selling (in part based on Nortel code that has been patched over the last decade with new features), thus the lies and lack of investment.

Other than that, attributing malice to someone just because it's a Chinese company is probably inappropriate.
