Fix this by using READ_ONCE()\nwhen fetching the pointer, and take bus' drivers klist lock to make sure\ndriver instance will not disappear while we access it.\n\nUse WRITE_ONCE() when setting the driver pointer to ensure there is no\ntearing.","modified":"2026-04-01T05:20:12.984303Z","published":"2025-05-08T07:15:50Z","upstream":["CVE-2025-37800"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-37800"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"5.15.200.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-63788.json"}}],"schema_version":"1.7.5"}
