runc: opencontainers/selinux: container escape and denial of service due to arbitrary write gadgets and procfs write redirects

A flaw was found in runc. This attack is a more sophisticated variant of CVE-2019-16884, which was a flaw that allowed an attacker to trick runc into writing the LSM process labels for a container process into a dummy tmpfs file and thus not apply the correct LSM labels to the container process...

Improper Access Control

github.com/opencontainers/runc is vulnerable to improper access control. The vulnerability is due to insufficient validation when bind-mounting /dev/pts/$n to /dev/console after pivotroot, which allows an attacker to manipulate mount paths and gain writable access to sensitive locations,...

MGASA-2025-0271 Updated opencontainers-runc packages fix security vulnerabilities

The way masked paths are implemented in runc can be exploited to cause the host system to crash or halt CVE-2025-31133 and a flaw in /dev/console bind-mounts can lead to container escape CVE-2025-52565. Also, arbitrary write gadgets and procfs write redirects could be used to engineer container...

CVE-2025-52565

runc is a CLI tool for spawning and running containers according to the OCI specification. Versions 1.0.0-rc3 through 1.2.7, 1.3.0-rc.1 through 1.3.2, and 1.4.0-rc.1 through 1.4.0-rc.2, due to insufficient checks when bind-mounting /dev/pts/$n to /dev/console inside the container, an attacker can...

CVE-2025-31133

runc is a CLI tool for spawning and running containers according to the OCI specification. In versions 1.2.7 and below, 1.3.0-rc.1 through 1.3.1, 1.4.0-rc.1 and 1.4.0-rc.2 files, runc would not perform sufficient verification that the source of the bind-mount i.e., the container's /dev/null was...

runc 1.1.13 and earlier as well as 1.2.0-rc2 and earlier can be tricked into creating empty files or directories in arbitrary locations in the host filesystem by sharing a volume between two containers and exploiting a race with os.MkdirAll. While this can be used to create empty files, existing...
