Fragnesia Linux Kernel Flaw Enables Root Privilege Gain
Security researchers have disclosed a newly identified local privilege escalation vulnerability in the Linux Kernel, dubbed “Fragnesia,” which belongs to the broader Dirty Frag family of flaws. The issue, officially tracked as CVE-2026-46300, affects the Linux Kernel’s XFRM ESP-in-TCP subsystem and allows unprivileged local attackers to escalate privileges to root by corrupting page-cache memory. The discovery of Fragnesia highlights
After the security vulnerabilities Copy Fail and Dirty Frag, a third critical vulnerability has now been found. Via "Fragnesia" attackers can get root rights. Affected are all systems that are also vulnerable to Dirty Frag. Fragnesia named vulnerability goes back to a bug in the kernel modules esp4 and esp6 for ESP/XFRM. They help encrypt Internet connections.
From "Linus' Law" to the era of autonomous agents: How OpenAI and Claude's tools are accelerating the discovery of critical flaws like Fragnesia, Dirty Frag, and Copy Fail. - on macitynet.it AI finds three vulnerabilities in the Linux kernel
Following Dirty Frag, Fragnesia, and other Linux kernel vulnerabilities exposed in recent days, the latest vulnerability is ssh-keysign-pwn. Through ssh-keysign-pwn, unprivileged users can read Ro...
Meet Fragnesia, the third Linux kernel vulnerability in a month
Linux admins reeling from handling last month’s CopyFail and last week’s Dirty Frag kernel vulnerabilities have a new headache to deal with: Fragnesia. “This is a significant vulnerability,” Robert Beggs, head of incident response firm DigitalDefence, told CSO. “It is bypassing traditional filesystem permissions that are present and enforced (for example, ‘file is owned by root’, or ‘file is read-only’) to allow manipulation without touching the…
