A remote attacker could exploit some of these vulnerabilities to trigger denial of service condition, elevation of privilege and security restriction bypass on the targeted system.<\/p>\n<p>\u00a0<\/p>\n<p><strong>Note:\u00a0<\/strong><\/p>\n<p>CVE-2026-31431 is being exploited in the wild. 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>\u00a0<\/p>\n<p><strong>[Updated on 2026-06-03]<\/strong><\/p>\n<p>Updated Description, System \/ Technologies affected, Solutions, Vulnerability Identifier and Related Links.<\/p>\n<p><a href=\"https:\/\/www.hkcert.org\/security-bulletin\/ubuntu-linux-kernel-multiple-vulnerabilities_20260602\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Ubuntu Linux Kernel Multiple Vulnerabilities https:\/\/www.hkcert.org\/security-bulletin\/ubuntu-linux-kernel-multiple-vulnerabilities_20260602 Publish Date: 2026-06-01 22:38:00 Source Domain: www.hkcert.org Multiple vulnerabilities&#8230;<\/p>\n","protected":false},"author":1,"featured_media":262598,"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":[90,31,71,57,79,27],"class_list":["post-262597","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-linux","tag-cve","tag-exploit","tag-linux","tag-security","tag-ubuntu","tag-vulnerability"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/262597"}],"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=262597"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/262597\/revisions"}],"predecessor-version":[{"id":262599,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/262597\/revisions\/262599"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/262598"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=262597"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=262597"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=262597"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
