kernel: "Fragnesia" is a variant of Dirty Frag vulnerability in the ESP/XFRM leading to Local Privilege Escalation (LPE) vulnerability in the Linux kernel

A flaw was found in the Linux kernel's XFRM ESP-in-TCP subsystem. Unsafe in-place cryptographic processing allows a low-privileged local attacker to write arbitrary bytes into the page cache of read-only files, including sensitive system files. An attacker can exploit this to overwrite privileged...
