CVE-2026-43284 / "Dirty Frag" .. Antoher one of those nasty local-privilege-escallations.

Quickfix for Centos/Fedora based systems:

printf 'install esp4 /bin/false\ninstall esp6 /bin/false\ninstall rxrpc /bin/false\n' > /etc/modprobe.d/dirtyfrag.conf && rmmod esp4 esp6 rxrpc 2>/dev/null; true

Caution: That also effectively disables IPSEC and AFS client support. But it can easily be reverted by removing the file when a patched kernel arrives.

Apparently there's yet another #LinuxKernel Local Privilege Escalation #vulnerability. There's a mitigation that disables esp4, esp6 and rxrpc modules.
