AI-suggested

Until a fix is available, users should be aware of the potential for misleading output from the id utility when real and effective UIDs differ and verify user identity information through alternative means if critical decisions depend on it.

Description

CVE-2026-35371 is a low-severity vulnerability in the id utility of uutils coreutils where the "pretty print" output misrepresents the effective user information. The utility incorrectly uses the effective group ID (GID) instead of the effective user ID (UID) when performing a name lookup for the effective user. This causes misleading diagnostic output that may lead to incorrect decisions about file permissions or access control by automated scripts or system administrators.
