Descriptions
In the Linux kernel, the following vulnerability has been resolved: hwrng: amd - Fix PCI device refcount leak for_each_pci_dev() is implemented by pci_get_device(). The comment of
pci_get_device() says that it will increase the reference count for the
returned pci_dev and also decrease the reference count for the input
pci_dev @from if it is not NULL. If we break for_each_pci_dev() loop with pdev not NULL, we need to call
pci_dev_put() to decrease the reference count. Add the missing
pci_dev_put() for the normal and error path.
The SUSE Linux Enterprise 15 SP5 RT kernel was updated to fix various security issues.
