          "details": "Not affected: the pam_access code shipped with CentOS 8.4 (PAM 1.3.1) only accepts remote “from” tokens that are IP addresses or network/netmask values and validates them with isipaddr(), and does not resolve arbitrary tokens as hostnames. CVE-2024-10963 requires hostname interpretation of access.conf rules; that behavior was introduced by a later upstream change (present in CentOS Stream 8 ELS) and is absent in the CentOS 8.4 build, so the vulnerable code path is not reachable.",
