en	This release is an emergency release to fix a security vulnerability in the *Linux* kernel.

en	Changes and updates

en	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.

en	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.

en	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.

en	- Update *Thunderbird* to [91.12.0](https://www.thunderbird.net/en-US/thunderbird/91.12.0/releasenotes/).
