Fragnesia centers around a separate bug within the ESP\/XFRM code with a logic bug to allow arbitrary byte writes into the kernel page cache of read-only files.\n<\/p>\n<p>Proof of concept code for Fragnesia is already out there. There is a two-line patch for addressing the issue within the Linux kernel&#8217;s skbuff.c code. That patch hasn&#8217;t yet been mainlined or picked up by any mainline kernel releases but presumably will be in short order for addressing this local privilege escalation issue.<br \/>\n<\/p>\n<p align=\"center\"><img decoding=\"async\" src=\"https:\/\/www.phoronix.net\/image.php?id=2026&#038;image=fragnesia\" alt=\"Fragnesia logo\"\/><\/p>\n<p>More details on the oss-security list.<br \/>\n<br \/><a href=\"https:\/\/www.phoronix.com\/news\/Linux-Fragnesia\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Fragnesia Made Public As Latest Linux Local Privilege Escalation Vulnerability https:\/\/www.phoronix.com\/news\/Linux-Fragnesia Publish Date: 2026-05-13 11:52:00&#8230;<\/p>\n","protected":false},"author":1,"featured_media":245331,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"fifu_image_url":"https:\/\/www.phoronix.net\/image.php?id=2026&image=fragnesia","fifu_image_alt":"","footnotes":""},"categories":[48],"tags":[31,71,57,27],"class_list":["post-245329","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-linux","tag-exploit","tag-linux","tag-security","tag-vulnerability"],"_links":{"self":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/245329"}],"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=245329"}],"version-history":[{"count":1,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/245329\/revisions"}],"predecessor-version":[{"id":245333,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/posts\/245329\/revisions\/245333"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media\/245331"}],"wp:attachment":[{"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/media?parent=245329"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/categories?post=245329"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/news-you-need.com\/index.php\/wp-json\/wp\/v2\/tags?post=245329"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
