CVE-2026-30892 (GCVE-0-2026-30892)

Vulnerability from cvelistv5 – Published: 2026-03-25 23:57 – Updated: 2026-03-26 18:10
VLAI
Title
Crun incorrectly parses `crun exec` option `-u`, leading to privilege escalation
Summary
crun is an open source OCI Container Runtime fully written in C. In versions 1.19 through 1.26, the `crun exec` option `-u` (`--user`) is incorrectly parsed. The value `1` is interpreted as UID 0 and GID 0 when it should have been UID 1 and GID 0. The process thus runs with higher privileges than expected. Version 1.27 patches the issue.
