Fragnesia: Linux Kernel Local Privilege Escalation via ESP-in-TCP

Researchers have identified a page-cache corruption vulnerability in the Linux kernel's Dirty Frag family that allows unprivileged local attackers to escalate privileges to root level. The vulnerability exploits issues in how the kernel handles fragmented data structures in memory. This represents a significant local privilege escalation pathway that affects Linux systems across multiple distributions.

Why it matters: Linux users and administrators need to patch affected systems immediately, as any local unprivileged user can exploit this to gain root access and fully compromise the machine.
