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...
