GHSA-CGRX-MC8F-2PRM runc container escape and denial of service due to arbitrary write gadgets and procfs write redirects

Impact This attack is primarily a more sophisticated version of CVE-2019-19921, which was a flaw which 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. The...

Race Condition Enabling Link Following

Overview Affected versions of this package are vulnerable to Race Condition Enabling Link Following via a race condition in the maskedPaths feature. An attacker can gain unauthorized access to host files, execute arbitrary code with elevated privileges, or cause a denial of service by manipulatin...

GHSA-9493-H29P-RFM2 runc container escape via "masked path" abuse due to mount race conditions

Impact The OCI runtime specification has a maskedPaths feature that allows for files or directories to be "masked" by placing a mount on top of them to conceal their contents. This is primarily intended to protect against privileged users in non-user-namespaced from being able to write to files o...

UBUNTU-CVE-2025-52881

runc is a CLI tool for spawning and running containers according to the OCI specification. In versions 1.2.7, 1.3.2 and 1.4.0-rc.2, an attacker can trick runc into misdirecting writes to /proc to other procfs files through the use of a racing container with shared mounts we have also verified thi...

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.18.0-rc2+ 721 Description An issue exists in the Linux kernel's F2FS filesystem implementation where an incorrect return value from the f2fs recover fsync data function can lead to a kernel panic. Specifically,...

USN-7851-1 runc-app, runc-stable vulnerabilities

Lei Wang and Li Fubang discovered that runC incorrectly handled masked paths. An attacker could possibly replace a container's /dev/null with a symlink to some other procfs file and possibly escape a container. CVE-2025-31133 Lei Wang and Li Fubang discovered that runC incorrectly handled the...
