But these devices may also have requeued\nrequests, leaving their requests stuck from not being kicked and causing\nthe removal process of the device to hang.\n\nscsi_run_host_queues() needs to run against more devices than the macro\nshost_for_each_device() allows. Instead of using the too limiting\nscsi_device_get() state checks, only ignore devices in SDEV_DEL state or\nwhen unable to acquire a reference. Attempt to run the queues for all\nother devices when scsi_run_host_queues() is called.","published":"2026-07-19T16:17:40.000Z","lastModified":"2026-10-19T21:17:18.000Z","status":"Modified","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-772","CWE-400"],"affected":["linux/linux kernel"],"epss":{"score":0.00441,"percentile":0.38093,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.44%).
