  "description": "In the Linux kernel, the following vulnerability has been resolved:  netfilter: conntrack: revert ct extension genid infrastructure  This infrastructure is not used anymore after moving ct timeout and helper to use datapath refcount to track object use.  Revert commit c56716c69ce1 (\u0022netfilter: extensions: introduce extension genid count\u0022) this patch disables all ct extensions (leading to NULL) for unconfirmed conntracks, when this is only targeted at ct helper and ct timeout. There is also codebase that dereferences the ct extension without checking for NULL which could lead to crash.",
