This release is an emergency release to fix critical security vulnerabilities in the Linux kernel and the expat XML library.
Changes and updates
- Update the Linux kernel to 6.12.100, which fixes CVE-2026-64560, a vulnerability that could allow Tor Browser in Tails to gain administrator privileges.
For example, if a malicious website that you visit is able to exploit CVE-2026-64560, they might take full control of your Tails and deanonymize you.
This attack is very unlikely but could be performed by a strong attacker, such as a government or a hacking firm. We are not aware of this attack being used in practice until now.
- Update the expat XML library to 2.8.2, which fixes DSA-6404-1, a set of vulnerabilities that could allow different applications in Tails to gain administrator privileges.
For example, if an attacker tricks you into opening a malicious file in an application that uses expat , such as LibreOffice , Audacity , or Git , they might then use one of these vulnerabilities to take full control of your Tails and deanonymize you.
This attack is very unlikely but could be performed by a strong attacker, such as a government or a hacking firm. We are not aware of this attack being used in practice until now.
