CVE-2025-62596: Rust Procfs Myself Toctou Mount Racecve-2025-62596-rust-procfs-myself-toctou-mount-race

`Process::myself()` from the `procfs` crate performs component-by-component path resolution of `/proc/self` without anchoring to a pre-opened directory file descriptor. In environments with shared mount namespaces (container runtimes, sandbox code), an attacker can race the traversal by bind-mounting over an intermediate path component between a validation c

This TOCTOU window (CWE-363 / CWE-61) allows an attacker to replace the path with a symlink between close() and mount(), causing an arbitrary file to be bind-mounted and bypa
