Dirty Frag chains xfrm-ESP and RxRPC kernel vulnerabilities for local privilege escalation.

• •Two page-cache write flaws enabling kernel memory access and root privilege gain
• •Affects Ubuntu 24.04.4, RHEL 10.1, openSUSE, CentOS, AlmaLinux 10, Fedora 44
• •Deterministic logic bug with high success rate, no race conditions needed
