# [Tails 7.10.1](
https://tails.net/news/version_7.10.1/)
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](
https://www.cve.org/CVERecord?id=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](
https://security-tracker.debian.org/tracker/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.
* Compress automatic upgrades with `zstd` for a faster startup, as we already did for the USB image in [Tails 7.0](
https://tails.net/news/version_7.0/).
* Make USB images and automatic upgrades 70 MB smaller by removing unused firmware.
