Note that this is not\na huge bug as the driver implements its own locking, and does not\nimplement changing the number of queues, but we need to silence\nthe splat.","modified":"2026-04-02T08:28:33.442106Z","published":"2025-10-04T15:43:49.383Z","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-2022-50498.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/6ad1c94e1e7e374d88f0cfd77936dddb8339aaba"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6f1991a940b90753b34570f093a21dba366e8cc0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a845a0c4bdece2c0073ecea2fca7c4d5f0550f78"},{"type":"WEB","url":"https://git.kernel.org/stable/c/c0323c0fd07804d5874699e93f935cda0d989c67"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/50xxx/CVE-2022-50498.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-50498"},{"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":"4a5fe57e775188be96359a1934501be45fe5f705"},{"fixed":"6f1991a940b90753b34570f093a21dba366e8cc0"},{"fixed":"a845a0c4bdece2c0073ecea2fca7c4d5f0550f78"},{"fixed":"c0323c0fd07804d5874699e93f935cda0d989c67"},{"fixed":"6ad1c94e1e7e374d88f0cfd77936dddb8339aaba"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-50498.json"}}],"schema_version":"1.7.5"}
