CVE-2025-62596 youki container escape and denial of service due to arbitrary write gadgets and procfs write redirects

Youki is a container runtime written in Rust. In versions 0.5.6 and below, youki’s apparmor handling performs insufficiently strict write-target validation, and when combined with path substitution during pathname resolution, can allow writes to unintended procfs locations. While resolving a path...

CVE-2025-62161 youki container escape via "masked path" abuse due to mount race conditions

Youki is a container runtime written in Rust. In versions 0.5.6 and below, the initial validation of the source /dev/null is insufficient, allowing container escape when youki utilizes bind mounting the container's /dev/null as a file mask. This issue is fixed in version 0.5.7...

CVE-2025-62161

Summary: CVE-2025-62161 affects Youki container runtime prior to v0.5.7, where the initial validation of the host path /dev/null is insufficient when Youki bind-mounts the container’s /dev/null as a mask. This race/validation flaw can enable container escape under bind-mmount scenarios. Root caus...

youki container escape via "masked path" abuse due to mount race conditions

Impact youki utilizes bind mounting the container's /dev/null as a file mask. When performing this operation, the initial validation of the source /dev/null was insufficient. Specifically, we initially failed to verify whether /dev/null was genuinely present. However, we did perform validation to...

Race Condition Enabling Link Following

Overview Affected versions of this package are vulnerable to Race Condition Enabling Link Following in the handling of procfs file writes. An attacker can cause arbitrary writes to sensitive files or trigger a denial of service by redirecting write operations through race conditions and...

Race Condition Enabling Link Following

Overview Affected versions of this package are vulnerable to Race Condition Enabling Link Following due to insufficient checks when bind-mounting /dev/pts/$n to /dev/console inside the container. An attacker can gain unauthorized write access to sensitive files within the container environment by...

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

Impact This attack is very similar in concept and application to CVE-2025-31133, except that it attacks a similar vulnerability in a different target namely, the bind-mount of /dev/pts/$n to /dev/console as configured for all containers that allocate a console. In runc version 1.0.0-rc3 and later...

Race Condition Enabling Link Following

Overview github.com/opencontainers/runc/libcontainer is a package for a modern container runtime. 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,...

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...
