CVE-2023-54323

A race condition was found in the CXL persistent memory driver. Rapid module load/unload cycles can cause async nvdimm device registration to run after the CXL context has been torn down, resulting in a NULL pointer dereference.

This affects CXL-capable systems with persistent memory. Triggering requires rapid module insertion/removal cycles, which is not typical in production but can occur during testing or development.
