{"id":"CVE-2022-50868","summary":"hwrng: amd - Fix PCI device refcount leak","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nhwrng: amd - Fix PCI device refcount 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() for the normal and error path.","modified":"2026-04-02T08:28:48.755007Z","published":"2025-12-30T12:15:39.211Z","related":["SUSE-SU-2026:0263-1","SUSE-SU-2026:0317-1","SUSE-SU-2026:0411-1","SUSE-SU-2026:0473-1","SUSE-SU-2026:0617-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50868.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1199f8e02941b326c60ab71a63002b7c80e38212"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2b79a5e560779b35e1164d57ae35c48b43373082"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2e10ecd012ae2b2a374b34f307e9bc1e6096c03d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/526c316948819d3ecd2bb20fe5e2580c51a1b760"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5998e5c30e839f73e62cb29e0d9617b0d16ccba3"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cb348c7908631dd9f60083a0a1542eab055d3edf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e246f5eff26055bdcb61a2cc99c50af72a19680f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ecadb5b0111ea19fc7c240bb25d424a94471eb7d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f1c97f72ffd504f49882774e2ab689d982dc7afc"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50868.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-50868"},{"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":"96d63c0297ccfd6d9059c614b3f5555d9441a2b3"},{"fixed":"f1c97f72ffd504f49882774e2ab689d982dc7afc"},{"fixed":"526c316948819d3ecd2bb20fe5e2580c51a1b760"},{"fixed":"e246f5eff26055bdcb61a2cc99c50af72a19680f"},{"fixed":"1199f8e02941b326c60ab71a63002b7c80e38212"},{"fixed":"5998e5c30e839f73e62cb29e0d9617b0d16ccba3"},{"fixed":"2b79a5e560779b35e1164d57ae35c48b43373082"},{"fixed":"cb348c7908631dd9f60083a0a1542eab055d3edf"},{"fixed":"2e10ecd012ae2b2a374b34f307e9bc1e6096c03d"},{"fixed":"ecadb5b0111ea19fc7c240bb25d424a94471eb7d"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-50868.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.6.18"},{"fixed":"4.9.337"}]},{"type":"ECOSYSTEM","events":[{"introduced":"4.10.0"},{"fixed":"4.14.303"}]},{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.19.270"}]},{"type":"ECOSYSTEM","events":[{"introduced":"4.20.0"},{"fixed":"5.4.229"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"5.10.163"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.86"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.0.16"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.1.0"},{"fixed":"6.1.2"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-50868.json"}}],"schema_version":"1.7.5"}
