CVE-2022-50659

In the Linux kernel, the following vulnerability has been resolved: hwrng: geode - Fix PCI device refcount leak foreachpcidev is implemented by pcigetdevice. The comment of pcigetdevice says that it will increase the reference count for the returned pcidev and also decrease the reference count fo...

CVE-2022-50659

The CVE-2022-50659 issue concerns the AMD Geode hwrng driver in the Linux kernel. A reference-count leak could occur when breaking out of the for_each_pci_dev() loop: pci_get_device() increases the returned pci_dev's refcount, but the corresponding pci_dev_put() was omitted along normal or error ...
