    Description

      Add protection during changelog record copy. The size of the changelog is not currently checked, which could cause memory corruption. There is a "TODO" comment mentioning something similar, "check changelog_rec_size" which was added in https://review.whamcloud.com/c/fs/lustre-release/+/18900 when the original code was written.
