The third major Linux kernel flaw in two weeks has been found - thanks to AI

AI is exposing Linux security holes faster than developers can patch them. Fragnesia is the latest. Here's what we know about it.

Dirty Frag gets a sequel as Fragnesia hands Linux attackers root-level access

Linux admins hoping Dirty Frag was a one-off horror from the kernel networking stack are about to have a considerably worse week. Researchers at Wiz have published an analysis of "Fragnesia," a Linux kernel local privilege escalation flaw discovered by William Bowling of the V12 security team that allows unprivileged users to gain root by corrupting page cache memory. The bug, tracked as CVE-2026-46300, has public proof-of-concept exploit code d…

New Fragnesia Linux flaw lets attackers gain root privileges

Linux distros are rolling out patches for a new high-severity kernel privilege escalation vulnerability (known as Fragnasia and tracked as CVE-2026-46300) that allows attackers to run malicious code as root.

New Fragnesia Linux Kernel LPE Grants Root Access via Page Cache Corruption

Details have emerged about a new variant of the recent Dirty Frag Linux local privilege escalation (LPE) vulnerability that allows local attackers to gain root access, making it the third such bug to be identified in the kernel within a span of two weeks. Codenamed Fragnesia, the security vulnerability is tracked as CVE-2026-46300 (CVSS score: 7.8) and is rooted in the Linux kernel's XFRM

New Linux Kernel Vulnerability Enables Root Access

A newly disclosed Linux kernel vulnerability dubbed Fragnesia allows any local unprivileged user to escalate privileges to root without requiring a race condition, making it one of the more reliable local privilege escalation exploits seen in recent years. Discovered by William Bowling of the V12 security team, Fragnesia joins a growing class of dangerous kernel
