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, 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.
