CVE-2024-41085

CVE-2024-41085 concerns the Linux kernel CXL memory region probing. The bug was a NULL pointer dereference when auto-assembling a pmem region during endpoint port probing because cxl_nvd (NVDIMM) was not yet registered. The fix changes the probe sequence so the cxl_nvd is available before or duri...
