Copy Fail (CVE-2026-31431) is a logic bug in the Linux kernel&#8217;s authencesn cryptographic template. It lets an unprivileged local user trigger a deterministic, controlled 4-byte write into the page cache of any readable file on the system. A single 732-byte Python script can edit a setuid binary and obtain root on essentially all Linux distributions shipped since 2017.<\/p>\n<p><a href=\"https:\/\/www.hkcert.org\/security-bulletin\/redhat-linux-kernel-multiple-vulnerabilities_20260508\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>RedHat Linux Kernel Multiple Vulnerabilities https:\/\/www.hkcert.org\/security-bulletin\/redhat-linux-kernel-multiple-vulnerabilities_20260508 Publish Date: 2026-05-07 22:05:00 Source Domain: www.hkcert.org Multiple vulnerabilities&#8230;<\/p>\n","protected":false},"author":1,"featured_media":242307,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/www.hkcert.org\/f\/bulletin_type\/100001\/1200c630\/og-image-operation-systems-linux.jpg","fifu_image_alt":"","footnotes":""},"categories":[48],"tags":[90,31,71,57],"class_list":["post-242306","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-linux","tag-cve","tag-exploit","tag-linux","tag-security"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/242306"}],"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=242306"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/242306\/revisions"}],"predecessor-version":[{"id":242308,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/242306\/revisions\/242308"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/242307"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=242306"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=242306"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=242306"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
