# [Tails 7.9.1](
https://tails.net/news/version_7.9.1/)
# Changes and updates
* Update _Tor Browser_ to [15.0.17](
https://blog.torproject.org/new-release-tor-browser-15017/).
* Update the _Tor_ client to 0.4.9.11.
* Update the _Linux_ kernel to 6.12.94, which fixes [CVE-2026-43503](
https://www.cve.org/CVERecord?id=CVE-2026-43503) (_DirtyClone_) and [CVE-2026-46331](
https://www.cve.org/CVERecord?id=CVE-2026-46331) (_PACKET_EDIT_MEME_), vulnerabilities that could allow an application in Tails to gain administration privileges.
For example, if an attacker was able to exploit other unknown security
vulnerabilities in an application included in Tails, they might then use
CVE-2026-46331 to take full control of your Tails and deanonymize you.
This attack is unlikely, but could be performed by a strong attacker, such as
a government or a hacking firm. We are not aware of this vulnerability being
used in practice until now.
