CVE-2026-48982

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-2026-48983 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...

CVE-2026-48983

CVE-2026-48983 affects pam_usb prior to version 0.9.2, where a TOCTOU race in per-device and per-user pad directory creation can be exploited via a symlink substitution. pam_usb performs a check-then-act using lstat() followed by mkdir(), allowing a local attacker to replace the target path with ...

CVE-2026-48982

CVE-2026-48982 affects pam_usb prior to version 0.9.2, where updating a one-time pad file creates a temporary file with open() lacking O_EXCL, enabling a race between concurrent processes to update the same pad. This non-atomicity can cause the stored pad to diverge from expectations, potentially...

CVE-2026-48984
