# [Tails 5.3.1 is
out](
https://tails.boum.org/news/version_5.3.1/index.en.html)
This release is an emergency release to fix a security vulnerability in the
_Linux_ kernel.
# Changes and updates
* Update the _Linux_ kernel to 5.10.127-2, which fixes [CVE-2022-34918](
https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2022-34918), a vulnerability that allows applications in Tails to gain administration privileges.
For example, if an attacker was able to exploit other unknown security
vulnerabilities in _Tor Browser_ , they might then use CVE-2022-34918 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 the wild.
* Update _Thunderbird_ to [91.12.0](
https://www.thunderbird.net/en-US/thunderbird/91.12.0/releasenotes/).
