{"id":"DEBIAN-CVE-2025-22068","details":"In the Linux kernel, the following vulnerability has been resolved:  ublk: make sure ubq-\u003ecanceling is set when queue is frozen  Now ublk driver depends on `ubq-\u003ecanceling` for deciding if the request can be dispatched via uring_cmd & io_uring_cmd_complete_in_task().  Once ubq-\u003ecanceling is set, the uring_cmd can be done via ublk_cancel_cmd() and io_uring_cmd_done().  So set ubq-\u003ecanceling when queue is frozen, this way makes sure that the flag can be observed from ublk_queue_rq() reliably, and avoids use-after-free on uring_cmd.","modified":"2026-08-27T23:05:13.684352720Z","published":"2025-04-16T15:16:01Z","upstream":["CVE-2025-22068"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2025-22068"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.25-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-22068.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.12.25-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2025-22068.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
