In the Linux kernel, the following vulnerability has been resolved: cxl/ras: Fix CPER handler device confusion By inspection, cxl_cper_handle_prot_err() is making a series of fragile assumptions that can lead to crashes: 1/ It assumes that endpoints identified in the record are a CXL-type-3 device, nothing guarantees that. 2/ It assumes that the device is bound to the cxl_pci driver, nothing guarantees that. 3/ Minor, it holds the device lock over the switch-port tracing for no reason as the trace is 100% generated from data in the record. Correct those by checking that the PCIe endpoint paren
