CVE-2026-30892

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.

Summary		(es) crun es un entorno de ejecución de contenedores OCI de código abierto escrito íntegramente en C. En las versiones 1.19 a 1.26, la opción `-u` (`--user`) de `crun exec` se analiza de forma incorrecta. El valor `1` se interpreta como UID 0 y GID 0, cuando debería haber sido UID 1 y GID 0. Por lo tanto, el proceso se ejecuta con privilegios más elevados de lo esperado. La versión 1.27 corrige el problema.
