{"id":"AZL-102810","summary":"CVE-2026-90168 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nksmbd: retain connection for pending notify work\n\nDeferred CHANGE_NOTIFY work keeps an async message ID after the original\nrequest work is released. A durable handle can outlive its connection, so\nthe connection teardown can destroy its async IDA before the handle close\nreleases the pending notify work.\n\nGive the synthetic deferred work a connection reference. Release it after\nthe async ID in ksmbd_free_work_struct(). This keeps the async IDA alive\nuntil the deferred work is released, even when the original connection has\nalready left the connection list.\n\nDuring server shutdown there is no client to receive a cleanup response.\nSkip the write and only release the pending work.","modified":"2026-09-18T14:16:36.682497582Z","published":"2026-09-17T17:17:10Z","upstream":["CVE-2026-90168"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90168"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-102810.json"}}],"schema_version":"1.9.0"}
