CVE-2026-48980 pam_usb: getenv() used in PAM context allows environment variable injection into local-check logic

pamusb provides hardware authentication for Linux using removable media. In versions prior to 0.9.2, getenv environment variables XRDPSESSION, DISPLAY and TMUX allow environment variable injection into local-check logic. These environment variables influence whether a current session is local or...
