NVD Description

Note: Versions mentioned in the description apply only to the upstream rv package and not the rv package as distributed by Centos. See How to fix? for Centos:10 relevant fixed versions and status.

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 module_init, so cxl_pci_driver_init()runs first. Whencxl_pci_probe()callsfwctl_register()and thendevice_add(), fwctl_class is not yet registered because fwctl_init() hasn't run, causing class_to_subsys()` to return NULL and skip knode_class initialization.

On device removal, class_to_subsys() returns non-NULL, and device_del() calls klist_del() on the uninitialized knode, triggering a NULL pointer dereference.
