CVE-2026-35356: Uutils Coreutils

Medium severity, CVSS 6.3. EPSS: 0.1% chance of exploitation in the next 30 days.

A Time-of-Check to Time-of-Use (TOCTOU) vulnerability exists in the install utility of uutils coreutils when using the -D flag. The command creates parent directories and subsequently performs a second path resolution to create the target file, neither of which is anchored to a directory file descriptor. An attacker with concurrent write access can replace a path component with a symbolic link between these operations, redirecting the privileged write to an arbitrary file system location.

Affected products

• Uutils Coreutils: before 0.7.0 (fixed in 0.7.0)
