CVE-2026-35357
The cp utility in uutils coreutils is vulnerable to an information disclosure race condition.
Published Apr 22, 2026 · updated Jun 17, 2026 · uutils coreutils
The cp utility in uutils coreutils is vulnerable to an information disclosure race condition. Destination files are initially created with umask-derived permissions (e.g., 0644) before being restricted to their final mode (e.g., 0600) later in the process. A local attacker can race to open the file during this window; once obtained, the file descriptor remains valid and readable even after the permissions are tightened, exposing sensitive or private file contents.
