Add the missing\npci_dev_put() to avoid refcount leak.","modified":"2026-04-02T08:28:35.396790Z","published":"2025-10-07T15:19:14.528Z","related":["SUSE-SU-2025:4111-1","SUSE-SU-2025:4139-1","SUSE-SU-2025:4149-1","SUSE-SU-2025:4320-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50520.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/1079df6acf56f99d86b0081a38c84701412cc90e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3991d98a8a07b71c02f3a39f77d6d9a7f575a5c4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/470a77989037c3ab2b08bf2d026d2c0ddc35ff5b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6f28c7f67af4ef9bca580ab67ae2d4511797af56"},{"type":"WEB","url":"https://git.kernel.org/stable/c/725a521a18734f65de05b8d353b5bd0d3ca4c37a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/88c6e0995c04b170563b5c894c50a3b2152e18c2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a6cffe54064a5f6c2162a85af3c16c6b453eac4e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b9decada8749b606fd8b4f04a3d6c74f7983d7bc"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e738f82e5b1311e8fb3d1409491a6fcce6418fbe"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50520.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-50520"},{"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":"c61e2775873f603148e8e998a938721b7d222d24"},{"fixed":"6f28c7f67af4ef9bca580ab67ae2d4511797af56"},{"fixed":"e738f82e5b1311e8fb3d1409491a6fcce6418fbe"},{"fixed":"1079df6acf56f99d86b0081a38c84701412cc90e"},{"fixed":"470a77989037c3ab2b08bf2d026d2c0ddc35ff5b"},{"fixed":"3991d98a8a07b71c02f3a39f77d6d9a7f575a5c4"},{"fixed":"88c6e0995c04b170563b5c894c50a3b2152e18c2"},{"fixed":"b9decada8749b606fd8b4f04a3d6c74f7983d7bc"},{"fixed":"a6cffe54064a5f6c2162a85af3c16c6b453eac4e"},{"fixed":"725a521a18734f65de05b8d353b5bd0d3ca4c37a"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0"},{"last_affected":"61ebf0a926149cc161131470cf848cb70b3d6fe6"},{"last_affected":"0a1d9a860832a5ca43114cdebf0e8650463cc1f0"},{"last_affected":"5f54f145719f453dccc73304cd427096bf7b806c"},{"last_affected":"063ab9cb6308a0806d623c8d6dda5cb2b3b87fce"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-50520.json"}}],"schema_version":"1.7.5"}
