CVE-2026-35368
Description
A flaw was found in uutils coreutils. The chroot utility, when used with the --userspec option, resolves user specifications after entering a restricted environment (chroot) but before relinquishing root privileges. This can cause the Name Service Switch (NSS), a system for resolving system information, to load malicious shared libraries from the new restricted directory if an attacker has write access. Successful exploitation allows an attacker to execute arbitrary code as root, potentially leading to privilege escalation or a full container escape.
