{"id":"CVE-2022-48973","summary":"gpio: amd8111: Fix PCI device reference count leak","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ngpio: amd8111: Fix PCI device reference count leak\n\nfor_each_pci_dev() is implemented by pci_get_device(). The comment of\npci_get_device() says that it will increase the reference count for the\nreturned pci_dev and also decrease the reference count for the input\npci_dev @from if it is not NULL.\n\nIf we break for_each_pci_dev() loop with pdev not NULL, we need to call\npci_dev_put() to decrease the reference count. Add the missing\npci_dev_put() after the 'out' label. Since pci_dev_put() can handle NULL\ninput parameter, there is no problem for the 'Device not found' branch.\nFor the normal path, add pci_dev_put() in amd_gpio_exit().","modified":"2026-04-02T08:27:11.339619Z","published":"2024-10-21T20:05:53.769Z","related":["SUSE-SU-2024:3983-1","SUSE-SU-2024:3985-1","SUSE-SU-2024:4082-1","SUSE-SU-2024:4100-1","SUSE-SU-2024:4131-1","SUSE-SU-2024:4364-1","SUSE-SU-2025:0034-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/48xxx/CVE-2022-48973.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/4271515f189bd5fe2ec86b4089dab7cb804625d2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/45fecdb9f658d9c82960c98240bc0770ade19aca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/4749c5cc147c9860b96db1e71cc36d1de1bd3f59"},{"type":"WEB","url":"https://git.kernel.org/stable/c/48bd5d3801f6b67cc144449d434abbd5043a6d37"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5ee6413d3dd972930af787b2c0c7aaeb379fa521"},{"type":"WEB","url":"https://git.kernel.org/stable/c/71d591ef873f9ebb86cd8d053b3caee785b2de6a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b2bc053ebbba57a06fa655db5ea796de2edce445"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e364ce04d8f840478b09eee57b614de7cf1e743e"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/48xxx/CVE-2022-48973.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-48973"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"f942a7de047d8c599cc1a9a26293c8c7400450ea"},{"fixed":"4749c5cc147c9860b96db1e71cc36d1de1bd3f59"},{"fixed":"71d591ef873f9ebb86cd8d053b3caee785b2de6a"},{"fixed":"b2bc053ebbba57a06fa655db5ea796de2edce445"},{"fixed":"48bd5d3801f6b67cc144449d434abbd5043a6d37"},{"fixed":"5ee6413d3dd972930af787b2c0c7aaeb379fa521"},{"fixed":"4271515f189bd5fe2ec86b4089dab7cb804625d2"},{"fixed":"e364ce04d8f840478b09eee57b614de7cf1e743e"},{"fixed":"45fecdb9f658d9c82960c98240bc0770ade19aca"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-48973.json"}}],"schema_version":"1.7.5"}
