This triggers a warning in btrfs_free_device() and leaves\nthe transaction list referencing freed memory.\n\nDetach the device while holding chunk_mutex before releasing it.","modified":"2026-09-30T05:39:58Z","published":"2026-09-25T11:17:38Z","upstream":["CVE-2026-98091"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-98091"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-104841.json"}}],"schema_version":"1.9.0"}
