CVE-2026-35359

A Time-of-Check to Time-of-Use TOCTOU vulnerability in the cp utility of uutils coreutils allows an attacker to bypass no-dereference intent. The utility checks if a source path is a symbolic link using path-based metadata but subsequently opens it without the ONOFOLLOW flag. An attacker with...

UBUNTU-CVE-2026-35358

The cp utility in uutils coreutils, when performing recursive copies -R, incorrectly treats character and block device nodes as stream sources rather than preserving them. Because the implementation reads bytes into regular files at the destination instead of using mknod, device semantics are...

CVE-2026-35359

The CVE-2026-35359 entry describes a TOCTOU flaw in the cp utility of the uutils coreutils project. The cp command checks whether the source path is a symlink using metadata, then opens the path without O_NOFOLLOW, allowing a concurrent writer to swap a regular file for a symlink during the windo...

CVE-2026-35357 uutils coreutils cp Information Disclosure via Permission Handling Race

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...

CVE-2026-35350 uutils coreutils cp Unexpected Privileged Executable Creation with -p

The cp utility in uutils coreutils fails to properly handle setuid and setgid bits when ownership preservation fails. When copying with the -p preserve flag, the utility applies the source mode bits even if the chown operation is unsuccessful. This can result in a user-owned copy retaining origin...

CVE-2026-35350

The CVE-2026-35350 entry concerns the cp utility in uutils coreutils. When using -p (preserve), if chown fails, the tool applies the source’s mode bits, potentially producing a user-owned copy with privileged bits (setuid/setgid) and violating local security policies. This behavior differs from G...
