[PATCH openEuler-1.0-LTS] iommu/vt-d: Fix PCI device refcount leak in dmar_dev_scope_init()
by Guo Mengqi 04 Nov '24

From: Xiongfeng Wang <wangxiongfeng2(a)huawei.com> stable inclusion from stable-v4.19.268 commit 876d7bfb89273997056220029ff12b1c2cc4691d category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/IAYRE3 CVE: CVE-2022-49002 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 4bedbbd782ebbe7287231fea862c158d4f08a9e3 ] 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 error path to avoid reference count leak.
