CVE-2022-49011

CVE-2022-49011 involves a leak in the Linux kernel hwmon/coretemp code: the PCI device refcount was not decremented after use in nv1a_ram_new(), causing a refcount leak. The root cause is the PCI API’s behavior of returning a device with an incremented refcount, requiring the caller to call pci_d...
