This causes a NULL pointer dereference\nwhen sd_is_zoned() is called inside that function. Avoid this by removing\nthe call to sd_zbc_release_disk() in sd_probe() error path.\n\nThis change is safe and does not result in zone information memory leakage\nbecause the zone information for a zoned disk is allocated only when\nsd_revalidate_disk() is called, at which point sdkp->disk_dev is fully set,\nresulting in sd_disk_release() being called when needed to cleanup a disk\nzone information using sd_zbc_release_disk().","published":"2025-02-26T07:01:14.000Z","lastModified":"2026-06-17T05:17:52.000Z","status":"Modified","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":{"version":"3.1","score":5.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-476"],"affected":["linux/linux kernel"],"epss":{"score":0.00268,"percentile":0.18817,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.27%).
