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...
