removable media security

About this tag
Removable media security covers the risks and mitigations associated with USB drives, SD cards, and other portable storage. Recent discussions highlight critical vulnerabilities such as CVE-2025-40307 in the Linux exFAT driver, which could allow data loss via crafted filesystems, and CVE-2025-49721, a heap buffer overflow in Windows' Fast FAT driver enabling local privilege escalation. Additionally, enabling AutoPlay in Windows 11 offers convenience but introduces security trade-offs, as it can automatically execute actions from untrusted media. Administrators and users should apply patches promptly, disable AutoPlay when not needed, and validate media sources to reduce exposure to these threats.
