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...

CVE-2026-45108

Himmelblau is an interoperability suite for Microsoft Azure Entra ID and Intune. From 2.0.0 to before 3.1.5 and 2.3.11, Himmelblau contained an authentication bypass vulnerability in the Device Authorization Grant DAG flow that allowed a user within the same Entra ID domain to obtain a local Unix...

CVE-2026-47269

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.0, pamusb's denyremote feature checks utmpx utaddrv6 to detect whether an authentication request originates from a remote session. The outer guard was if utent-utaddrv60 != 0, which only tests the first...

CVE-2026-47272

pam_usb for Linux allows local authentication bypass before version 0.9.0 due to pusb_pad_compare() only checking the user-side pad (~/.pamusb/device.pad) and not requiring the system-side pad on the USB device to be present. A local user can delete or obscure their own device.pad to bypass the U...

CVE-2026-47272 pam_usb: OTP pad authentication bypass via missing system pad check and uninitialized RNG buffer

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-2026-32650

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.1, when a PAM service is configured with denyremote=false in pamusb commonly done for display managers such as gdm-password or lightdm to bypass process/TTY heuristics for local sessions, the PAMRHOST...

CVE-2026-48064

Summary: pam_usb prior to 0.9.1 allowed a remote XDMCP session to bypass USB authentication when deny_remote=false, because the PAM_RHOST check was gated inside the deny_remote branch. Technical details (supported): pam_usb provides hardware authentication for Linux via removable media. In affect...
