CVE-2025-65105 – Apptainer ineffective application of selinux and apparmor –security options

CVE ID : CVE-2025-65105

Published : Dec. 2, 2025, 5:49 p.m. | 37 minutes ago

Description : Apptainer is an open source container platform. In Apptainer versions less than 1.4.5, a container can disable two of the forms of the little used –security option, in particular the forms –security=apparmor: and –security=selinux: which otherwise put restrictions on operations that containers can do. The –security option has always been mentioned in Apptainer documentation as being a feature for the root user, although these forms do also work for unprivileged users on systems where the corresponding feature is enabled. Apparmor is enabled by default on Debian-based distributions and SElinux is enabled by default on RHEL-based distributions, but on SUSE it depends on the distribution version. This vulnerability is fixed in 1.4.5.

Severity: 0.0 | NA
