CVE-2026-48985
pamusb provides hardware authentication for Linux using ordinary removable media. In versions 0.9.1 and below, pusbisloginctllocal can cause a NULL dereference crash when parsing loginctl output. The function calls popen and reads the result; if the Remote field is only a newline, fgets succeeds...
CVE-2026-48984
pam_usb for Linux (affected: v0.9.1 and earlier) has a memory handling flaw where xfree() frees buffers without zeroing contents, potentially leaving sensitive data (including one-time pad bytes) in freed heap memory. On systems with use-after-free or heap inspection capabilities, this could perm...
CVE-2026-44711
pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.8.7, symlink attacks on pad directory and pad files enable authentication bypass and root file corruption. This vulnerability is fixed in 0.8.7...
CVE-2026-44710
pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.8.7, src/device.c passed the return values of udisksdrivegetserial, udisksdrivegetvendor, and udisksdrivegetmodel directly to strcmp without NULL checks. The GIO/UDisks API documentation states these...

EUVD-2026-32656
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...
