Don't bother reading the article, read the write-up the article author attempted to paraphrase (poorly) at https://www.crowdstrike.com/wp-content/uploads/2024/08/Channel-File-291-Incident-Root-Cause-Analysis-08.06.2024.pdf https://www.crowdstrike.com/wp-content/uploads/2024/08/Chann... The way I read it was that they coded up this template type that could take 21 parameters. They expected it to take up to 21 parameters, but an intermediate representation expected it to have only 20. The code path which read the 21st parameter was not covered by tests nor the first deployed rapid response content using this template type. When they ran the untested code for the first time, kaboom.
