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...

runc: container escape via 'masked path' abuse due to mount race conditions

A flaw was found in runc. This flaw exploits an issue with how masked paths are implementedin runc. When masking files, runc will bind-mount the container's /dev/null inode on top of the file. However, if an attacker can replace /dev/null with a symlink to some other procfs file, runc will instea...

runc: container escape with malicious config due to /dev/console mount and related races

A flaw was found in runc. CVE-2025-52565 is very similar in concept and application toCVE-2025-31133, except that it exploits a flaw in /dev/console bind-mounts. When creating the /dev/console bind-mount to /dev/pts/$n, if an attacker replaces /dev/pts/$n with a symlink then runc will bind-mount...

Improper Input Validation

github.com/opencontainers/runc is vulnerable to improper input validation. The vulnerability is due to insufficient verification of the bind-mount source /dev/null, which allows an attacker to exploit it via arbitrary mount manipulation, leading to host information disclosure, denial of service,...

Improper File Access

runc is vulnerable to improper file access. The vulnerability is due to insufficient validation of write targets in /proc during concurrent container execution with shared mounts, which allows an attacker to exploit race conditions and redirect writes to unintended procfs files...
