CVE-2026-35370 Details
Description
The id utility in uutils coreutils miscalculates the groups= section of its output. The implementation uses a user's real GID instead of their effective GID to compute the group list, leading to potentially divergent output compared to GNU coreutils. Because many scripts and automated processes rely on the output of id to make security-critical access-control or permission decisions, this discrepancy can lead to unauthorized access or security misconfigurations.
A vulnerability exists in the id utility of uutils coreutils, where it incorrectly calculates the groups section of its output. The issue arises because the implementation uses a user's real GID instead of the effective GID, leading to discrepancies compared to GNU coreutils. This miscalculation can cause security-critical scripts and automated processes to make flawed access-control or permission decisions, potentially resulting in unauthorized access or security misconfigurations.
Users can switch to GNU coreutils to avoid this vulnerability, as the issue does not exist in that version.
