CVE-2026-3184
A flaw was found in util-linux. Improper hostname canonicalization in the `login(1)` utility, when invoked with the `-h`
A flaw was found in util-linux. Improper hostname canonicalization in the login(1) utility, when invoked with the -h option, can modify the supplied remote hostname before setting PAM_RHOST. A remote attacker could exploit this by providing a specially crafted hostname, potentially bypassing host-based Pluggable Authentication Modules (PAM) access control rules that rely on fully qualified domain names.
This could lead to unauthorized access.
