What is CVE-2026-56852?

A vulnerability exists in the Go language's norm.Iter component where it fails to properly handle input containing invalid UTF-8 byte sequences. This oversight allows an attacker to exploit the input handling mechanism, potentially causing the system to enter an infinite loop. Such behavior can lead to service disruption, as the application may become unresponsive while processing malformed input. It is crucial for users of the Go language to ensure their implementations are updated to mitigate this risk.
