CVE-2026-56852 is an infinite-loop vulnerability in the Go golang.org/x/text/unicode/norm package. The Unicode normalization iterator, norm.Iter, can fail to make forward progress while handling truncated or otherwise invalid UTF-8 byte sequences. An affected application that passes attacker-controlled malformed UTF-8 to normalization functionality can hang in the iterator.
