| CVE-2025-6020 | Hig | 0.51 | 7.8 | 0.00 | Jun 17, 2025 | A flaw was found in linux-pam. The module pam_namespace may use access user-controlled paths without proper protection, allowing local users to elevate their privileges to root via multiple symlink attacks and race conditions. | ||
| CVE-2024-10963 | Hig | 0.48 | 7.4 | 0.01 | Nov 7, 2024 | A flaw was found in pam_access, where certain rules in its configuration file are mistakenly treated as hostnames. This vulnerability allows attackers to trick the system by pretending to be a trusted hostname, gaining unauthorized access. This issue poses a risk for systems… | ||
| CVE-2015-3238 | Med | 0.42 | 6.5 | 0.03 | Aug 24, 2015 | The _unix_run_helper_binary function in the pam_unix module in Linux-PAM (aka pam) before 1.2.1, when unable to directly access passwords, allows local users to enumerate usernames or cause a denial of service (hang) via a large password. | ||
