Tails 7.10.1 is an emergency release addressing two critical security vulnerabilities. The Linux kernel is updated to 6.12.100, patching CVE-2026-64560, which could allow Tor Browser to gain administrator privileges and potentially deanonymize users. The expat XML library is updated to 2.8.2, fixing DSA-6404-1, a set of privilege escalation vulnerabilities exploitable via malicious files in apps like LibreOffice, Audacity, or Git. Both attack vectors are considered unlikely but feasible by sophisticated actors such as governments or hacking firms. The release also compresses automatic upgrades with zstd for faster startup and reduces USB image size by 70 MB by removing unused firmware.
