pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.8.7, src/tmux.c reads the user's $TMUX environment variable, splits it on commas, and interpolates the socket-path component directly into a shell command passed to popen. Because the value is placed insi...

CVE-2026-47270 pam_usb: strtok() race condition in multi-threaded PAM hosts can corrupt deny_remote result

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.0, pamusb is a PAM module loaded into the host process sudo, login, GDM, GNOME Shell. Display managers such as GDM run multiple concurrent authentication threads. Three functions used by the denyremote...

CVE-2026-47270

CVE-2026-47270 affects the pam_usb PAM module used for Linux hardware authentication. The denial logic (deny_remote) uses non-reentrant strtok(), with three functions sharing a global token pointer; in multi-threaded authentication (e.g., long-lived display managers like GDM), two concurrent auth...

CVE-2026-47274 pam_usb: Uncontrolled search path in pam_usb tools allows privilege escalation via PATH manipulation

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.0, multiple pamusb helper tools resolved external binaries through the PATH environment variable rather than using absolute paths. An attacker who can influence the process environment during PAM...

CVE-2026-47274

CVE-2026-47274 affects pam_usb on Linux prior to 0.9.0. The issue stems from several pam_usb helper tools resolving external binaries via PATH instead of absolute paths, enabling a local attacker to substitute malicious binaries when they can influence the process environment during PAM authentic...

CVE-2026-48066 pam_usb: Thread-unsafe static pointer in log.c causes data race under concurrent PAM authentication

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.1, src/log.c contains a process-wide static pointer that is written on every PAM invocation with the address of a stack-local variable. This violates the PAM re-entrancy requirement and creates a data...

CVE-2026-48066

pam_usb fixes a thread-unsafe behavior: before 0.9.1, src/log.c used a process-wide static pointer written on every PAM invocation to a stack-local address, creating a data race when PAM is invoked concurrently by multiple threads. The issue is resolved in version 0.9.1. Affected component: pam_u...
