You are a security professional working closely with the organization's IT team. The organization uses several Linux based servers with open source tools. As the team is downloading the files for the new system build, you do a check of the MD$5$ hashes for the tools. The MD$5$ hash value for one of the source files on the download website is listed as a$6$cdf$2$f$550$e$3$e$69$eb$0$b$46$dfae$1$cbe$7$db$.$ After downloading the source file and manually hashing it$,$ you get a hash value of $93f5641$ ed$107$dafd$3$bc$8$bd$3$db$9$df$13$fd$.$ What does this mean and does it present any security risk?

Open source files don't use hash values to verify their authenticity. The difference in hash values does not present a security issue.

The source file hashes don't match indicating that something has changed within the file. Because the hash value does not match the listed hash value on the website it is not safe to use the file due to potential file tampering.

The file hash values don't have to match and don't have anything to do with the security of a file.

The source file hashes don't match meaning that there has been some change to the file. It is probably just an updated version of the file and presents no real danger.
