CVE-2026-82429: Description The setuid-root `worker-launcher` binary adjusts ownership and permissions of worker directories by walking

A vulnerability exists in the `worker-launcher` binary (a program that runs with root privileges) that allows an attacker to redirect file ownership and permission changes to arbitrary files on the system. By replacing directory names with symbolic links (shortcuts to other files or directories) between when the system checks a file and when it modifies it, an untrusted user can trick the root-privileged program into modifying files they shouldn't be able to access. This attack can be repeated as many times as needed.
