Fragnesia Linux Privilege Escalation is a high-severity logic flaw in the Linux kernel's socket buffer handling (skb_try_coalesce()) within the XFRM/ESP-in-TCP subsystem (espintcp ULP).
An unprivileged local attacker can achieve arbitrary byte writes into the kernel page cache of any readable file — including system binaries like /usr/bin/su — leading to reliable local root privilege escalation.
