This risk is especially relevant for a system designed for anonymity and session isolation.<\/p>\n<p class=\"wp-block-paragraph\">Tails explains that if an attacker exploited another unknown vulnerability in a Tails application, the kernel flaw could be used to take full control of the session and potentially deanonymize the user.<\/p>\n<p>Tails 7.8.1<\/p>\n<p class=\"wp-block-paragraph\">The project stresses that such an attack is unlikely and would require a strong attacker, such as a government or hacking firm. It also says it is not aware of the vulnerability being used in practice.<\/p>\n<p class=\"wp-block-paragraph\">To address the issue, Tails 7.8.1 updates the Linux kernel to version 6.12.90-2. The release also updates the Tor client to 0.4.9.9, which fixes several Tor security vulnerabilities.<\/p>\n<p class=\"wp-block-paragraph\">For additional details, refer to the\u00a0changelog or the release announcement.<\/p>\n<p class=\"wp-block-paragraph\">Automatic upgrades are available from Tails 7.0 or later to Tails 7.8.1. Users who cannot complete the automatic upgrade, or whose system fails to start afterward, are advised to perform a manual upgrade instead.<\/p>\n<p class=\"wp-block-paragraph\">The project also notes that users installing Tails 7.8.1 on a new USB stick ought to follow the installation instructions, but warns that Persistent Storage on the USB stick will be lost if they install instead of upgrading.<\/p>\n<p><a href=\"https:\/\/linuxiac.com\/tails-7-8-1-emergency-release-fixes-serious-linux-kernel-flaw\/\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Tails 7.8.1 Emergency Release Fixes Serious Linux Kernel Flaw https:\/\/linuxiac.com\/tails-7-8-1-emergency-release-fixes-serious-linux-kernel-flaw\/ Publish Date: 2026-06-04 08:36:00 Source&#8230;<\/p>\n","protected":false},"author":1,"featured_media":264096,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/linuxiac.com\/wp-content\/uploads\/2026\/06\/tails781.jpg","fifu_image_alt":"","footnotes":""},"categories":[48],"tags":[90,89,71,57,27],"class_list":["post-264095","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-linux","tag-cve","tag-flaw","tag-linux","tag-security","tag-vulnerability"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/264095"}],"collection":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/comments?post=264095"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/264095\/revisions"}],"predecessor-version":[{"id":264098,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/264095\/revisions\/264098"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/264096"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=264095"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=264095"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=264095"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
