CVE-2026-48980

The PAM module pam_usb is affected by a local-access vulnerability in earlier releases (pre-0.9.2) where getenv() in a PAM context returns attacker-controlled values for XRDP_SESSION, DISPLAY, and TMUX when the environment is manipulated by a local user. These values influence local-vs-remote ses...

EUVD-2026-37937

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...

CVE-2026-48983 pam_usb: TOCTOU race condition in pad directory creation allows symlink substitution

pamusb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, a symlink race condition exists in per-device and per-user pad directory creation. pamusb uses a check-then-act pattern: it calls lstat to test for existence and then calls mkdir separate...

EUVD-2026-37935

pamusb provides hardware authentication for Linux using ordinary removable media. In versions prior to 0.9.2, when updating a one-time pad file, a temporary file is created using open without the OEXCL flag. Without OEXCL, the create operation is not atomic: two concurrent processes racing to...

CVE-2026-54411 Linux-PAM pam_userdb Observable Timing Discrepancy in Plaintext Password Comparison

Linux-PAM through 1.7.2 contains an observable timing discrepancy CWE-208 in the pamuserdb module's plaintext-password comparison path in modules/pamuserdb/pamuserdb.c that allows a local or network-adjacent attacker able to repeatedly drive authentication through a calling service to recover the...

CVE-2026-47272

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.0, the pusbpadcompare function in src/pad.c only verified that the user-side pad /.pamusb/device.pad could be read, but did not enforce that the system-side pad the pad file on the USB device was also...

EUVD-2026-32652

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.0, pamusb builds XPath expressions from user-supplied identifiers PAM username, service name and device-supplied identifiers USB device serial, model, vendor to query /etc/pamusb.conf. These identifiers...

CVE-2026-48792 pam_usb: pusb_has_virtual_input_device() silently discards EACCES, disabling remote desktop detection under non-root execution

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.1, src/evdev.c silently ignores EACCES errors when opening /dev/input/event nodes, causing pusbhasvirtualinputdevice to return 0 no virtual devices found even when every open call failed due to...

pam_usb 安全漏洞

pamusb is a Linux hardware authentication tool developed by McDope’s individual developer, based on USB devices. Versions of pamusb prior to 0.9.1 contained security vulnerabilities. These vulnerabilities stemmed from the silent ignoring of EACCES errors in the src/evdev.c file. This could lead t...

PT-2026-44113

Name of the Vulnerable Software and Affected Versions pam usb versions prior to 0.8.7 Description In the src/tmux.c file, the software reads the $TMUX environment variable, splits it by commas, and interpolates the socket-path component directly into a shell command executed via the popen functio...

pam_usb 代码问题漏洞

pamusb is a Linux hardware authentication tool developed by McDope’s individual developer, based on USB devices. Versions of pamusb prior to 0.8.7 have code vulnerabilities. This vulnerability stems from the fact that in src/device.c, the return values of udisksdrivegetserial, udisksdrivegetvendo...
