CVE-2026-79994 is a time-of-check to time-of-use race condition in the guest-to-host Unix-domain socket relay of Docker Sandboxes. The relay verifies that a guest-selected Unix-socket pathname is within an authorized workspace, then later resolves that pathname again when establishing the connection. A malicious sandbox guest can replace an intermediate directory with a symbolic link in the interval between validation and connection, causing the host-side relay to resolve the path outside the authorized workspace and connect to an arbitrary reachable pathname-based AF_UNIX socket. Docker Sandboxes versions 0.37.0 through 0.41.9 are affected.

A high-severity Docker Sandboxes Unix-domain-socket relay race condition that allows a guest to bypass workspace path validation and access sensitive host IPC capabilities, potentially enabling arbitrary host command execution.
A high-severity symlink race condition in Docker Sandboxes' guest-to-host Unix-domain-socket relay. A sandbox guest can redirect a host connection from an authorized workspace socket path to an arbitrary AF_UNIX socket outside the workspace, potentially exposing host-side data or capabilities.
A high-severity TOCTOU symlink race in Docker Sandboxes' guest-to-host Unix domain socket relay. A malicious guest may cause the host to connect to an arbitrary AF_UNIX socket outside the authorized workspace, potentially exposing data or enabling access to host-side service functions.
A high-severity time-of-check to time-of-use symlink race in the Docker Sandboxes guest-to-host Unix-domain socket relay. A malicious guest can potentially cause the host to connect to an arbitrary AF_UNIX socket outside the authorized workspace, exposing data or host-side service functions.
