CVE-2022-50615

CVE-2022-50615 affects the Linux kernel’s perf/x86/intel/uncore code. The root cause is a reference-count leak in snr_uncore_mmio_map() where pci_get_device() increases the pci_dev reference count and snr_uncore_get_mc_dev() returns a pci_dev with an extra reference. The fix is to call pci_dev_pu...
