  "description": "In the Linux kernel, the following vulnerability has been resolved:  fwctl: Fix class init ordering to avoid NULL pointer dereference on device removal  CXL is linked before fwctl in drivers/Makefile. Both use \u0060module_init, so \u0060cxl_pci_driver_init()\u0060 runs first. When \u0060cxl_pci_probe()\u0060 calls \u0060fwctl_register()\u0060 and then \u0060device_add()\u0060, fwctl_class is not yet registered because fwctl_init() hasn\u0027t run, causing \u0060class_to_subsys()\u0060 to return NULL and skip knode_class initialization.  On device removal, \u0060class_to_subsys()\u0060 returns non-NULL, and \u0060device_del()\u0060 calls \u0060klist_del()\u0060 on the uninitialized knode, triggering a NULL pointer dereference.",
