{"id":"AZL-102449","summary":"CVE-2026-90216 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nubi: Fix rollback for explicit UBI device numbers\n\nubi_init_attach() rolls back module initialization failures by scanning\nubi_devices[0..i-1], where i is the mtd= parameter index. That assumes\nthe parameter index matches the UBI device number.\n\nThat assumption is not true when mtd= specifies an explicit ubi_num. A\nsuccessfully attached device can be stored at a higher ubi_devices[]\nslot, and a later failure can miss it during rollback.\n\nScan the full ubi_devices[] array and detach by the actual array index,\nmatching the way UBI devices are stored.","modified":"2026-09-18T14:16:34.251599562Z","published":"2026-09-17T17:17:16Z","upstream":["CVE-2026-90216"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90216"}],"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-102449.json"}}],"schema_version":"1.9.0"}
